IR: Give 'DI' prefix to debug info metadata Finish off PR23080 by renaming the debug info IR constructs from `MD*` to `DI*`. The last of the `DIDescriptor` classes were deleted in r235356, and the last of the related typedefs removed in r235413, so this has all baked for about a week. Note: If you have out-of-tree code (like a frontend), I recommend that you get everything compiling and tests passing with the *previous* commit before updating to this one. It'll be easier to keep track of what code is using the `DIDescriptor` hierarchy and what you've already updated, and I think you're extremely unlikely to insert bugs. YMMV of course. Back to *this* commit: I did this using the rename-md-di-nodes.sh upgrade script I've attached to PR23080 (both code and testcases) and filtered through clang-format-diff.py. I edited the tests for test/Assembler/invalid-generic-debug-node-*.ll by hand since the columns were off-by-three. It should work on your out-of-tree testcases (and code, if you've followed the advice in the previous paragraph). Some of the tests are in badly named files now (e.g., test/Assembler/invalid-mdcompositetype-missing-tag.ll should be 'dicompositetype'); I'll come back and move the files in a follow-up commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236120 91177308-0d34-0410-b5e6-96231b3b80d8

[opaque pointer type] Add textual IR support for explicit type parameter to getelementptr instruction One of several parallel first steps to remove the target type of pointers, replacing them with a single opaque pointer type. This adds an explicit type parameter to the gep instruction so that when the first parameter becomes an opaque pointer type, the type to gep through is still available to the instructions. * This doesn't modify gep operators, only instructions (operators will be handled separately) * Textual IR changes only. Bitcode (including upgrade) and changing the in-memory representation will be in separate changes. * geps of vectors are transformed as: getelementptr <4 x float*> %x, ... ->getelementptr float, <4 x float*> %x, ... Then, once the opaque pointer type is introduced, this will ultimately look like: getelementptr float, <4 x ptr> %x with the unambiguous interpretation that it is a vector of pointers to float. * address spaces remain on the pointer, not the type: getelementptr float addrspace(1)* %x ->getelementptr float, float addrspace(1)* %x Then, eventually: getelementptr float, ptr addrspace(1) %x Importantly, the massive amount of test case churn has been automated by same crappy python code. I had to manually update a few test cases that wouldn't fit the script's model (r228970,r229196,r229197,r229198). The python script just massages stdin and writes the result to stdout, I then wrapped that in a shell script to handle replacing files, then using the usual find+xargs to migrate all the files. update.py: import fileinput import sys import re ibrep = re.compile(r"(^.*?[^%\w]getelementptr inbounds )(((?:<\d* x )?)(.*?)(| addrspace\(\d\)) *\*(|>)(?:$| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$))") normrep = re.compile( r"(^.*?[^%\w]getelementptr )(((?:<\d* x )?)(.*?)(| addrspace\(\d\)) *\*(|>)(?:$| *(?:%|@|null|undef|blockaddress|getelementptr|addrspacecast|bitcast|inttoptr|\[\[[a-zA-Z]|\{\{).*$))") def conv(match, line): if not match: return line line = match.groups()[0] if len(match.groups()[5]) == 0: line += match.groups()[2] line += match.groups()[3] line += ", " line += match.groups()[1] line += "\n" return line for line in sys.stdin: if line.find("getelementptr ") == line.find("getelementptr inbounds"): if line.find("getelementptr inbounds") != line.find("getelementptr inbounds ("): line = conv(re.match(ibrep, line), line) elif line.find("getelementptr ") != line.find("getelementptr ("): line = conv(re.match(normrep, line), line) sys.stdout.write(line) apply.sh: for name in "$@" do python3 `dirname "$0"`/update.py < "$name" > "$name.tmp" && mv "$name.tmp" "$name" rm -f "$name.tmp" done The actual commands: From llvm/src: find test/ -name *.ll | xargs ./apply.sh From llvm/src/tools/clang: find test/ -name *.mm -o -name *.m -o -name *.cpp -o -name *.c | xargs -I '{}' ../../apply.sh "{}" From llvm/src/tools/polly: find test/ -name *.ll | xargs ./apply.sh After that, check-all (with llvm, clang, clang-tools-extra, lld, compiler-rt, and polly all checked out). The extra 'rm' in the apply.sh script is due to a few files in clang's test suite using interesting unicode stuff that my python script was throwing exceptions on. None of those files needed to be migrated, so it seemed sufficient to ignore those cases.

Move the complex address expression out of DIVariable and into an extra argument of the llvm.dbg.declare/llvm.dbg.value intrinsics. Previously, DIVariable was a variable-length field that has an optional reference to a Metadata array consisting of a variable number of complex address expressions. In the case of OpPiece expressions this is wasting a lot of storage in IR, because when an aggregate type is, e.g., SROA'd into all of its n individual members, the IR will contain n copies of the DIVariable, all alike, only differing in the complex address reference at the end. By making the complex address into an extra argument of the dbg.value/dbg.declare intrinsics, all of the pieces can reference the same variable and the complex address expressions can be uniqued across the CU, too. Down the road, this will allow us to move other flags, such as "indirection" out of the DIVariable, too. The new intrinsics look like this: declare void @llvm.dbg.declare(metadata %storage, metadata %var, metadata %expr) declare void @llvm.dbg.value(metadata %storage, i64 %offset, metadata %var, metadata %expr) This patch adds a new LLVM-local tag to DIExpressions, so we can detect and pretty-print DIExpression metadata nodes. What this patch doesn't do: This patch does not touch the "Indirect" field in DIVariable; but moving that into the expression would be a natural next step. http://reviews.llvm.org/D4919 rdar://problem/17994491 Thanks to dblaikie and dexonsmith for reviewing this patch!

Upgrade tests to the latest debug info format. Mostly this is just changing the named metadata (llvm.dbg.sp, llvm.dbg.gv, llvm.dbg.<func>.lv, etc -> llvm.dbg.cu), adding a few fields to older records (DIVariable: flags/inlined-at, DICompileUnit: sp/gv/types, DISubprogram: local variables list) The tests to update were discovered by a change I'm working on to remove debug info version support - so any tests using old debug info versions I haven't updated probably are bad tests or just not actually designed to test debug info. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176671 91177308-0d34-0410-b5e6-96231b3b80d8

; CHECK: Ldebug_loc0:
DebugInfo: Fix a bunch of tests that, owing to their compile_unit metadata not including a 13th field, had some subtle behavior. Without the 13th field, the "emission kind" field defaults to 0 (which is not equal to either of the values of the emission kind enum (1 == full debug info, 2 == line tables only)). In this particular instance, the comparison with "FullDebugInfo" was done when adding elements to the ranges list - so for these test cases no values were added to the ranges list. This got weirder when emitting debug_loc entries as the addresses should be relative to the range of the CU if the CU has only one range (the reasonable assumption is that if we're emitting debug_loc lists for a CU that CU has at least one range - but due to the above situation, it has zero) so the ranges were emitted relative to the start of the section rather than relative to the start of the CU's singular range. Fix these tests by accounting for the difference in the description of debug_loc entries (in some cases making the test ignorant to these differences, in others adding the extra label difference expression, etc) or the presence/absence of high/low_pc on the CU, and add the 13th field to their CUs to enable proper "full debug info" emission here. In a future commit I'll fix up a bunch of other test cases that are not so rigorously depending on this behavior, but still doing similarly weird things due to the missing 13th field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214937 91177308-0d34-0410-b5e6-96231b3b80d8

DwarfDebug: Emit number of bytes in .debug_loc entry directly Emit the number of bytes in a `.debug_loc` entry directly. The old code created temp labels (expensive), emitted the difference between them, and then emitted one on each side of the relevant bytes. (I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc` (the optimized version of ld64's `-save-temps` when linking the `verify-uselistorder` executable in an LTO bootstrap). I've hacked `MCContext::Allocate()` to just call `malloc()` instead of using the `BumpPtrAllocator` so that the heap profile is easier to read. As far as peak memory is concerned, `MCContext::Allocate()` is equivalent to a leak, since it only gets freed at process teardown. In my heap profile, this patch drops memory usage of `DwarfDebug::emitDebugLoc()` from 132.56 MB (11.4%) down to 29.86 MB (2.7%) at peak memory. Some of that must be noise from `SmallVector` (or other) allocations -- peak memory only dropped from 1160 MB down to 1100 MB -- but this nevertheless shaves 5% off the top.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236629 91177308-0d34-0410-b5e6-96231b3b80d8

This got weirder when emitting debug_loc entries as the addresses should be relative to the range of the CU if the CU has only one range (the reasonable assumption is that if we're emitting debug_loc lists for a CU that CU has at least one range - but due to the above situation, it has zero) so the ranges were emitted relative to the start of the section rather than relative to the start of the CU's singular range. Fix these tests by accounting for the difference in the description of debug_loc entries (in some cases making the test ignorant to these differences, in others adding the extra label difference expression, etc) or the presence/absence of high/low_pc on the CU, and add the 13th field to their CUs to enable proper "full debug info" emission here. In a future commit I'll fix up a bunch of other test cases that are not so rigorously depending on this behavior, but still doing similarly weird things due to the missing 13th field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214937 91177308-0d34-0410-b5e6-96231b3b80d8

DwarfDebug: Emit number of bytes in .debug_loc entry directly Emit the number of bytes in a `.debug_loc` entry directly. The old code created temp labels (expensive), emitted the difference between them, and then emitted one on each side of the relevant bytes. (I'm looking at `llc` memory usage on `verify-uselistorder.lto.opt.bc` (the optimized version of ld64's `-save-temps` when linking the `verify-uselistorder` executable in an LTO bootstrap). I've hacked `MCContext::Allocate()` to just call `malloc()` instead of using the `BumpPtrAllocator` so that the heap profile is easier to read. As far as peak memory is concerned, `MCContext::Allocate()` is equivalent to a leak, since it only gets freed at process teardown. In my heap profile, this patch drops memory usage of `DwarfDebug::emitDebugLoc()` from 132.56 MB (11.4%) down to 29.86 MB (2.7%) at peak memory. Some of that must be noise from `SmallVector` (or other) allocations -- peak memory only dropped from 1160 MB down to 1100 MB -- but this nevertheless shaves 5% off the top.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236629 91177308-0d34-0410-b5e6-96231b3b80d8

DebugInfo: Move new hierarchy into place Move the specialized metadata nodes for the new debug info hierarchy into place, finishing off PR22464. I've done bootstraps (and all that) and I'm confident this commit is NFC as far as DWARF output is concerned. Let me know if I'm wrong :). The code changes are fairly mechanical: - Bumped the "Debug Info Version". - `DIBuilder` now creates the appropriate subclass of `MDNode`. - Subclasses of DIDescriptor now expect to hold their "MD" counterparts (e.g., `DIBasicType` expects `MDBasicType`). - Deleted a ton of dead code in `AsmWriter.cpp` and `DebugInfo.cpp` for printing comments. - Big update to LangRef to describe the nodes in the new hierarchy. Feel free to make it better. Testcase changes are enormous. There's an accompanying clang commit on its way. If you have out-of-tree debug info testcases, I just broke your build. - `upgrade-specialized-nodes.sh` is attached to PR22564. I used it to update all the IR testcases. - Unfortunately I failed to find way to script the updates to CHECK lines, so I updated all of these by hand. This was fairly painful, since the old CHECKs are difficult to reason about. That's one of the benefits of the new hierarchy. This work isn't quite finished, BTW. The `DIDescriptor` subclasses are almost empty wrappers, but not quite: they still have loose casting checks (see the `RETURN_FROM_RAW()` macro). Once they're completely gutted, I'll rename the "MD" classes to "DI" and kill the wrappers. I also expect to make a few schema changes now that it's easier to reason about everything. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@231082 91177308-0d34-0410-b5e6-96231b3b80d8
