add new concrete versions for 1/2/4-byte mergable strings.

These are not actually created yet.

Remove ARM specific getInlineAsmLength. We'll rely on the simpler (and faster) generic algorithm for now. If more accurate computation is needed, we'll rely on the disassembler.

Emit sub r, #c instead of transforming it to add r, #-c if c fits in 8-bit. This is a bit of pre-mature optimization. 8-bit variant makes it likely it will be narrowed to a 16-bit instruction.

textual sections.

hey it uses .previous, so it should work :)

llvm-svn: 78004

more step towards "semantics sections"

llvm-svn: 78002

Add a testcase.

Thanks Chris.

This will cause it to enter the ".text" section instead of "_text"
but masm is already broken.

 - The theory is these should never actually be called, since these boil down to
   passes which can access the target data via the standard mechanism.

llvm_report_error already prints "LLVM ERROR:". So stop reporting errors like "LLVM ERROR: llvm: error:" or "LLVM ERROR: ERROR:".

Since we're generating stubs by hands we don't follow the ABI and don't
create a register spill area.
Don't use this area in compilation callback!

Add 'Indirect' LocInfo class and use to pass __m128 on win64. Also minore fixes here and there (mostly __m64).

llvm-svn: 77964

Cleanup Darwin MMX calling conv stuff - make the stuff more generic. This also fixes a subtle bug, when 6th v1i64 argument passed wrongly.

llvm-svn: 77963

Unbreak Win64 CC. Step one: honour register save area, fix some alignment and provide a different set of call-clobberred registers.

This is not just a matter of passing in the target triple from the module;
currently backends are making decisions based on the build and host
architecture. The goal is to migrate to making these decisions based off of the
triple (in conjunction with the feature string). Thus most clients pass in the
target triple, or the host triple if that is empty.

This has one important change in the way behavior of the JIT and llc.

For the JIT, it was previously selecting the Target based on the host
(naturally), but it was setting the target machine features based on the triple
from the module. Now it is setting the target machine features based on the
triple of the host.

For LLC, -march was previously only used to select the target, the target
machine features were initialized from the module's triple (which may have been
empty). Now the target triple is taken from the module, or the host's triple is
used if that is empty. Then the triple is adjusted to match -march.

The take away is that -march for llc is now used in conjunction with the host
triple to initialize the subtarget. If users want more deterministic behavior
from llc, they should use -mtriple, or set the triple in the input module.

Use the i12 variant of load / store opcodes if offset is zero. Now we pass all of multisource as well.
