Andrew Lenharth 53bb83bc43 who said we had to use the return address in the return address register. Might save a move in many cases

Chris Lattner 10594206f4 Add support to the X86 backend for emitting ELF files. To use this, we 
currently use: llc t.bc --filetype=obj

This will produce a t.o file which is dumpable with readelf.  Currently
the file produced is empty, but the scaffolding to do more is now in place.

Chris Lattner 386b151ce6 iniital checkin of ELFWriter implementation 
For now, the elf writer is only capable of emitting an empty elf file, with
a section table and a section table string table.  This will be enhanced
in the future :)

Andrew Lenharth dac0b3cb8a depend more on legalize putting constants on the RHS 
llvm-svn: 22289
 2005-06-26 23:01:11 +00:00
Andrew Lenharth 331380b2e2 With setOperationAction(ISD::UINT_TO_FP, MVT::i64, Expand), Legalize 
should be able to handle this case.  The code is there, so let's see
if it works.

Andrew Lenharth a4a12983cc more complete Lowering for vacopy and vaarg 
llvm-svn: 22274
 2005-06-22 23:04:28 +00:00
Andrew Lenharth 253145299b If we support structs as va_list, we must pass pointers to them to va_copy 
See last commit for LangRef, this implements it on all targets.

Andrew Lenharth 5305ea5c86 SelectionDAG is very unhappy when the argument to an intrinsic is a struct

Andrew Lenharth cf9008afea Make it easier to find alpha stuff in doxygen, and fixup labeling 
of memory instructions in the assembly, to allow later linking
of traces with LLVM Value*s.

John Criswell 9cb5a82cdc Fixed indentation. 
llvm-svn: 22270
 2005-06-20 19:59:22 +00:00
Andrew Lenharth d6bee05fc4 because some functions just use va_start and pass things to vfprintf

Andrew Lenharth 5488847304 the correct fix was to fix AliasAnalysis.getModRefInfo 
llvm-svn: 22268
 2005-06-20 15:25:22 +00:00
Andrew Lenharth f42d7b54c0 make AliasAnalysis know that VAArg writes memory. This is extremely conservative and should be fixed 
llvm-svn: 22267
 2005-06-20 15:24:23 +00:00
Andrew Lenharth 805d84a077 prevent GCSE from forwarding stores to loads around vaarg. This is uggly, and I am trying to fix the AliasInfo, as it should catch the problem instead.

llvm-svn: 22262
 2005-06-19 14:04:55 +00:00
Andrew Lenharth 237e6afde7 so this doesn't crash when run. It is hard to tell if things are right enough to work correctly with all the TmpInstructions running around 
llvm-svn: 22261

Reid Spencer ef0d7c6af6 Fix this test case to actually test the new va_arg instruction not the 
old vaarg instruction.

Andrew Lenharth a4c10cd6f2 OK, at least get rid of old stuff, and mark what needs to be fixed for V9

llvm-svn: 22252
 2005-06-18 18:30:37 +00:00
Andrew Lenharth 5fb787c619 OK, after checking the backwards compatibility code on X86 and the new code 
path on alpha, now has come the time for new vararg support.  So, with out
further ado, I revert behavior back a couple of years!

Well, ok, I lied.  A few more notes.

First, the Simple ISels cannot be expected to work any longer, but they
should still compile

Second, there are likely some bugs to track down once the nightly testers
start with this.

Third, the initial patch doesn't include sparcv9, but I'll do that today.

Forth, subsequent patches won't bother being long winded.

Reid Spencer 4fdd96c4e0 Clean up some uninitialized variables and missing return statements that 
GCC 4.0.0 compiler (sometimes incorrectly) warns about under release build.

llvm-svn: 22249
 2005-06-18 17:37:34 +00:00
Reid Spencer 1fb9d01919 Make sure a variable is initialized before use to clean up a warning from 
GCC 4.0.0 in release build.
