Chris Lattner eecd9b1d52 Revert r189704, which removed the guidance about not duplicating doc comments. 
This is under active discussion.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189730 91177308-0d34-0410-b5e6-96231b3b80d8
 2013-09-01 15:48:08 +00:00
Chris Lattner af069a8920 Remove the suggestion to not duplicate comments in header and 
implementation files.  While doc generation systems don't need this,
humans do benefit from it.  Not everyone reads all code through doxygen.

Chris Lattner 389ee19eab remove some @deprecated markers: LLVM APIs aren't deprecated, they are removed when obsolete. 
These APIs are still used, and the constant APIs are actually really important.

Removing these makes -Wdocumentation more useful.

Chris Lattner 03abfc7114 Disable the StringMapEntry copy constructor, to make sure we 
reject things like: "for (auto Entry : SomeStringMap)".  Previously
this would copy the value but not the tail allocated string data
(the key).

Chris Lattner a32bd682a0 Fix a nasty off-by one error that only manifests with 64-bit word size (which is 
not enabled yet).

 2013-02-09 07:37:26 +00:00
Chris Lattner b24f5b7c08 Fix the underlying problem that was causing read(0) to be called: sometimes the 
bitcode writer would generate abbrev records saying that the abbrev should be
filled with fixed zero-bit bitfields (this happens in the .bc writer when 
the number of types used in a module is exactly one, since log2(1) == 0).

In this case, just handle it as a literal zero.  We can't "just fix" the writer
without breaking compatibility with existing bc files, so have the abbrev reader
do the substitution.

Strengthen the assert in read to reject reads of zero bits so we catch such 
crimes in the future, and remove the special case designed to handle this.

Chris Lattner e001f27e5e recommit r173072 (preparing bitstream reader to read a machine word at a time, 
instead of always 32-bits at a time) with two changes:

1. Make Read(0) always return zero without affecting the state of our cursor.
2. Hack word_t to always be 32 bits, as staging.

These two caveats will change shortly.

 2013-02-09 06:52:14 +00:00
Chris Lattner dc60fc1aa7 r173072 is causing some regressions on big endian hosts, I don't have time to debug it 
so revert it for now.


git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173074 91177308-0d34-0410-b5e6-96231b3b80d8
 2013-01-21 19:08:15 +00:00
Chris Lattner 02b206f6d8 rework the Bitstream reader to actually work a machine word at a time, instead of 32-bits at a time. 
This cuts in half the number of virtual methods called to refill that word when compiling on a 64-bit
host, and will make 64-bit read operations faster.

Chris Lattner 69582cf6c4 Fix a heinous inefficiency introduced in r149918, wherein reading each byte of a 
BLOB (i.e., large, performance intensive data) in a bitcode file was switched to
invoking one virtual method call per byte read.  Now we do one virtual call per
BLOB.

 2013-01-21 18:24:49 +00:00
Chris Lattner 47543a8a66 wean Blob handling logic off of banging on NextChar directly. Instead, make 
it reason about the current bit position, which is always independent of the
underlying cursors word size.

Chris Lattner 5aaabbfe62 Extend the (abi-irrelevant) return convention to be able to return more than two values in 
integer registers.  This is already supported by the fastcc convention, but it doesn't
hurt to support it in the standard conventions as well.

In cases where we can cheat at the calling convention, this allows us to avoid returning
things through memory in more cases.

Chris Lattner 55dc5c77a3 Reimplement the intrinsic verifier to use the same table as Intrinsic::getDefinition, 
making it stronger and more sane.

Delete the code from tblgen that produced the old code.

Besides being a path forward in intrinsic sanity, this also eliminates a bunch of
machine generated code that was compiled into Function.o

Chris Lattner c32cef6aa1 These tests used intrinsics with the wrong prototype. They weren't caught because 
the old verifier just checked that something "was a pointer", but not that the pointee
was correct.

Chris Lattner 387c9dcdda enhance the intrinsic info stuff to emit encodings that don't fit in 32-bits into a 
separate side table, using the handy SequenceToOffsetTable class.  This encodes all
these weird things into another 256 bytes, allowing all intrinsics to be encoded this way.

Chris Lattner a98aa6ad1e Significantly reduce the compiled size of Functions.cpp by turning a big blob of tblgen

in follow-on patches.

the bugpoint as a standalone app, it should be more portable to search

2) bugpoint driver accounts opt plugins, but does not list them in the
final output command.
