Torok Edwin ce0c81e7dd Add regular expression matching support, based on OpenBSD regexec()/regcomp() 
implementation.

Torok Edwin 6493798d83 install-sh chmods to 0755 by default, and this causes 'git diff' to show 
that all the Makefiles changed mode.
Fix this by tellint install-sh to chmod
only to 0644, these are not executable files after all!

Torok Edwin 0debb15baf Remove the llvmprof.out from the test output, otherwise running 
make check in a non-clean directory causes it to fail (for example when running
make check twice), since execution counts will differ.

 2009-07-21 07:09:05 +00:00
Torok Edwin 969f28dfb6 Introduce a pointertracking pass. 
For now this only computes the allocated size of the memory pointed to by a
pointer, and offset a pointer from allocated pointer.
The actual checkLimits part will come later, after another round of review.

Torok Edwin c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

Torok Edwin 93990d775e After converting assert(0) to LLVM_UNREACHABLE we lost file/line location. 
Fix by making the LLVM_UNREACHABLE pass __FILE__ and __LINE__ to
llvm_unreachable.

Torok Edwin c25e7581b9 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

commit.

 2009-07-07 17:39:53 +00:00
Torok Edwin 31e2466f15 Introduce new error handling API. 
This will replace exit()/abort() style error handling with an API
that allows clients to register custom error handling hooks.
The default is to call exit(1) when no error handler is provided.

Torok Edwin 1970a89a49 Call doInitialization(), releaseMemory(), and doFinalization() for on-the-fly passes as well. 
Also don't call finalizers for LoopPass if initialization was not called.
Add a unittest that tests that these methods are called, in the proper
order, and the correct number of times.

Torok Edwin 7e55a00d06 for instructions with void type we have no choice but print the instruction as 
is, otherwise we get a <badref>.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72567 91177308-0d34-0410-b5e6-96231b3b80d8
 2009-05-29 10:28:44 +00:00
Torok Edwin 3f3c6d4e5b Add a DEBUG() output to GVN that prints the instruction clobbering a load. 
This is useful when trying to figure out why GVN didn't eliminate redundant
loads.

Torok Edwin 2efc73d5d0 For the new ar --plugin libLLVMgold.so to work we need libLTO linked with 
pthreads, otherwise ar complains of unresolved references to pthread_mutex_*.
LTO doesn't actually use pthreads, but ManagedStatic does.

Fix this by linking in LIBS (that contains pthreads) for LTO and gold.
For now this links in more libs than needed (libffi for example), we can figure
out later how to link in those libs per-tool later.

Add a comment explaining why the cache needs to be cleared.

 2009-05-24 19:36:09 +00:00
Torok Edwin b679de2a21 The rewriter may hold references to instructions that are deleted because they are trivially dead. 
Fix by clearing the rewriter cache before deleting the trivially dead
instructions.
Also make InsertedExpressions use an AssertingVH to catch these
bugs easier.

Torok Edwin 2c23501031 Make bugpoint emit a bugpoint-reduced-blocks.bc, because bugpoint itself

 2009-05-24 09:40:47 +00:00
Torok Edwin 23d471f62e Add -disable-global-remove option to bugpoint. 
Sometimes when bugpointing a crash the bugpoint-reduced-simplified.bc reproduces
a totally different bug than the original one ("GV doesn't have initializer").
Although its useful to report that bug too, I need a way to reduce the original
bug, hence I introduced -disable-global-remove.

Torok Edwin 6bb4958543 Fix PR4254. 
The DAGCombiner created a negative shiftamount, stored in an
unsigned variable. Later the optimizer eliminated the shift entirely as being
undefined.
Example: (srl (shl X, 56) 48). ShiftAmt is 4294967288.
Fix it by checking that the shiftamount is positive, and storing in a signed
variable.

 2009-05-23 14:06:57 +00:00
Torok Edwin 382cb2189a Revert this. There's no way to verifiy indirect calls, and an optimizer can turn 
indirect call into direct call, thus the verifier would reject something it
previously accepted.

Torok Edwin 9107c54693 Verify that calling conventions match function prototype. 
This only rejects mismatches between target specific calling convention
and C/LLVM specific calling convention.
There are too many fastcc/C, coldcc/cc42 mismatches in the testsuite, these are
not reject by the verifier.

Torok Edwin 4cdc44c82c Fix g++-4.4.0 warning, it was causing llvm-nm to fail on wrapped BC files: 
Path.cpp:59: warning: case label value exceeds maximum value for type
magic[0] is a (signed) char, but some case values are unsigned (e.g. 0xde).
When magic[0] was 0xde, the switch has taken the default branch instead of case
0xde branch.
Apparently this was the behaviour with older versions of gcc too, but not with g++.
Now g++-4.4 behaves as gcc, and ignores unsigned case values out of range signed
range.
