Daniel Dunbar c7c5f9fa86 llvm-mc/Mach-O: Add MCCodeEmitter support, for encoding instructions.
- No relocations yet, of course.

llvm-svn: 80235
2009-08-27 08:17:51 +00:00
Daniel Dunbar 981a71c302 llvm-mc/X86: Implement single instruction encoding interface for MC.
- Note, this is a gigantic hack, with the sole purpose of unblocking further
   work on the assembler (its also possible to test the mathcer more completely
   now).

 - Despite being a hack, its actually good enough to work over all of 403.gcc
   (although some encodings are probably incorrect). This is a testament to the 
   beauty of X86's MachineInstr, no doubt! ;)

Chris Lattner d3374e8dfd Implement a new optimization in the inliner: if inlining multiple
calls into a function and if the calls bring in arrays, try to merge
them together to reduce stack size.  For example, in the testcase
we'd previously end up with 4 allocas, now we end up with 2 allocas.

As described in the comments, this is not really the ideal solution
to this problem, but it is surprisingly effective.  For example, on
176.gcc, we end up eliminating 67 arrays at "gccas" time and another
24 at "llvm-ld" time.

One piece of concern that I didn't look into: at -O0 -g with
forced inlining this will almost certainly result in worse debug
info.  I think this is acceptable though given that this is a case
of "debugging optimized code", and we don't want debug info to
prevent the optimizer from doing things anyway.

Despite common miscomceptions, iterator.h is alive and well. It broke the build
bots for several hours. And yet no one bothered to look at them.

Gabor and Doug, please review your changes and make sure that they actually
build before resubmitting them.

Dan Gohman 352a49586d Add some checks for MachineCFG consistency. Use AnalyzeBranch and
do extra checking when it succeeds, as those are cases where
CodeGen will be doing particularly interesting CFG modifications.

Dan Gohman fb3d84b524 Initialize the PoisonMemory member before initializing

This fixes potential spurious (though probably otherwise
harmless) poising of unused memory, and fixes the
associated valgrind error.

2009-08-27 00:31:47 +00:00
Dan Gohman f1abb5511b Expand i8 selects into control flow instead of 16-bit conditional
moves. This avoids the need to promote the operands (or implicitly
extend them, a partial register update condition), and can reduce
i8 register pressure. This substantially speeds up code such as
write_hex in lib/Support/raw_ostream.cpp.

subclass-coalesce.ll is too trivial and no longer tests what it was
originally intended to test.

Daniel Dunbar e73b267301 llvm-mc/Mach-O: Don't put assembler temporary labels in the symbol table.
- I moved section creation back into AsmParser. I think policy decisions like
   this should be pushed higher, not lower, when possible (in addition the
   assembler has flags which change this behavior, for example).
