Andrew Lenharth d74877a46d Adapt the code for handling uint -> fp conversion for the 32 bit case to
handling it in the 64 bit case.  The two code paths should probably be merged.

Andrew Lenharth a50adcf57d So, it turns out I forgot that one valid way of restoring GP after a call
is to use RA, which assumes the called function uses RA for the register
holding the return address when it issues a ret.

Nate Begeman db32921535 Initial set of .td file changes necessary to get scalar fp in xmm registers
working.  The instruction selector changes will hopefully be coming later
this week once they are debugged.  This is necessary to support the darwin
x86 FP model, and is recommended by intel as the replacement for x87.  As
a bonus, the register allocator knows how to deal with these registers
across basic blocks, unliky the FP stackifier.  This leads to significantly
better codegen in several cases.

Andrew Lenharth 7aba58ab89 Reduce use of pseudo ops
Namely, output the rellocation flags explicitly when loading constants.
Added benifit: save a load when loading from the constant pool.

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 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.

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

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.
