Dale Johannesen 722212d1a0 Revise C library functions description to be vaguer, per Chris. 
llvm-svn: 82776
 2009-09-25 17:04:42 +00:00
Dale Johannesen 68f971b1d6 Clarify that llvm attaches C language semantics to 
functions with names that match the C library.

 2009-09-02 17:31:42 +00:00
Dale Johannesen 2aaf539564 Add an 'inline hint' attribute to represent source 
code hints that it would be a good idea to inline
a function ("inline" keyword).  No functional change
yet; FEs do not emit this and inliner does not use it.

 2009-08-26 01:08:21 +00:00
Chris Lattner e7f064ed2b improve documentation for linker_private linkage. 
llvm-svn: 79893
 2009-08-24 04:32:16 +00:00
Dan Gohman 2de532c132 Clarify a few things in the inbounds description. 
Describing inbounds in terms of infinitely precise arithmetic prohibits
the assumption address-space-sized integer arithmetic will wrap, with
a wrapped-around value landing within the same object.

 2009-07-20 22:41:19 +00:00
Chris Lattner 58f9bb2ccd implement a new magic global "llvm.compiler.used" which is like llvm.used, but 
doesn't cause ".no_dead_strip" to be emitted on darwin.

llvm-svn: 76399

llvm-svn: 76391
 2009-07-20 02:29:24 +00:00
Bill Wendling a3c6f6bffa Add plumbing for the `linker_private' linkage type. This type is meant for 
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

Chris Lattner fd8dea4c47 end sentence in period, draw attention to the fact that you should 
only do this if you are a crazy russian hacker. ;-)

llvm-svn: 76241

Anton Korobeynikov c8ce7b08ba Add support for naked functions 
llvm-svn: 76198
 2009-07-17 18:07:26 +00:00
Chris Lattner 7b9d6ebb9c remove llvm.part.set.* and llvm.part.select.*. They have never been 
implemented in codegen, have no frontend to generate them, and are 
better implemented with pattern matching (like the ppc backend does
to generate rlwimi/rlwinm etc).

 2009-07-12 21:08:53 +00:00
Nick Lewycky a21d3daadc Remove the vicmp and vfcmp instructions. Because we never had a release with 
these instructions, no autoupgrade or backwards compatibility support is
provided.

llvm-svn: 74991
 2009-07-08 03:04:38 +00:00
Duncan Sands 2ae473f739 Clarify that if the alignment is zero then an alignment 
compatible with the type will be used (at least the ABI
alignment).

llvm-svn: 73827
 2009-06-20 13:26:06 +00:00
Eli Friedman 8bc032c97c Remove the "llvm.umul.with.overflow is broken" warning; it should be 
essentially working now, at least for common cases, and it shouldn't 
silently generate bad code.

llvm-svn: 73089
 2009-06-08 22:17:53 +00:00
Dan Gohman a5b9645c4b Split the Add, Sub, and Mul instruction opcodes into separate 
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

Dan Gohman 9069d890e8 Add a note mentioning that uses of the return value of an invoke 
must be dominated by the normal label.

llvm-svn: 72285
 2009-05-22 21:47:08 +00:00
Nick Lewycky b8f9b7a965 Make MDNode use CallbackVH. Also change MDNode to store Value* instead of 
Constant* in preperation of a future change to support holding non-Constants
in an MDNode.
