Owen Anderson e2f23a3abf Add lengthof and endof templates that hide a lot of sizeof computations.

Dale Johannesen a47f7d7cfd Long double patch 8 of N: make it partially work in 
SSE mode (all but conversions <-> other FP types, I think):
>>Do not mark all-80-bit operations as "Requires[FPStack]"
(which really means "not SSE").
>>Refactor load-and-extend to facilitate this.
>>Update comments.
>>Handle long double in SSE when computing FP_REG_KILL.

Dale Johannesen 57c6ac5fe5 Long double patch 7 of N, unless I lost count:). 
Last x87 bits for full functionality (not
thoroughly tested, and long doubles do not work
in SSE modes at all - use -mcpu=i486 for now)

Dale Johannesen 75169a82d6 Get X86 long double calling convention to work 
(on Darwin, anyway).  Fix some table omissions for
LD arithmetic.

Dale Johannesen b1888e73ad Long double patch 4 of N: initial x87 implementation. 
Lots of problems yet but some simple things work.

Dale Johannesen a2b3c175db Fix for PR 1505 (and 1489). Rewrite X87 register 
model to include f32 variants.  Some factoring
improvments forthcoming.

Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Reid Spencer de46e48420 For PR786: 
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Chris Lattner f431ad4477 Rewrite FP stackifier support in the X86InstrInfo.td file, splitting patterns 
that were overloaded to work before and after the stackifier runs.  With the
new clean world, it is possible to write patterns for these instructions: woo!

This also adds a few simple patterns here and there, though there are a lot
still missing.  These should be easy to add though. :)

See the comments under "Floating Point Stack Support" for more details on
the new world order.

This patch as absolutely no effect on the generated code, woo!

Chris Lattner debae1e3c3 Allow the FP stackifier to completely ignore functions that do not use FP at 
all.  This should speed up the X86 backend fairly significantly on integer
codes.  Now if only we didn't have to compute livevar still... ;-)

All CVS history was renamed, the *,v were copied over.  No worries.
