| | | | | | | | | | | | | | | SSE, so we can't return floating point values if this is disabled. Detect this error for clang. With SSE1 only, f64 is a problem; it can be done, but neither llvm-gcc nor clang has ever generated correct code for it. Since nobody noticed this I think it's OK to treat it as an error for now. This also handles SSE-sized vectors of floating point. 8207686, 8204109. llvm-svn: 109201
* Fix some AVX instructions which didnt had HasAVX prefix. And also a problem ↵Bruno Cardoso Lopes2010-07-231-6/+8

* eliminate the TargetInstrInfo::GetInstSizeInBytes hook. Chris Lattner2010-07-224-5/+5
| | | | | | | | ARM/PPC/MSP430-specific code (which are the only targets that implement the hook) can directly reference their target-specific instrinfo classes. llvm-svn: 109171

| | | | | | | "yet another" copy of the dwarf EH emission code that was copied, pasted and slightly hacked up. llvm-svn: 109169
* Add remaining AVX instructions (most of them dealing with GR64 destinations. ↵Bruno Cardoso Lopes2010-07-221-5/+30
| | | | | | This complete the assembler support for the general AVX ISA. But we still miss instructions from FMA3 and CLMUL specific feature flags, which are now the next step llvm-svn: 109168
* remove the JIT "NeedsExactSize" feature and supporting logic.Chris Lattner2010-07-224-80/+3
| | | | llvm-svn: 109167
* switch a private implementation of GetFunctionSizeInBytes.Chris Lattner2010-07-221-1/+14
| | | | | | | | | This is probably not the best way to implement "Force LR to be spilled if the Thumb function size is > 2048." do this, it should use the branch shortening infrastructure, but I'm just preserving functionality here. llvm-svn: 109165
* X86MCInstLower now depends on AsmPrinter being around.Chris Lattner2010-07-222-32/+11
| | | | llvm-svn: 109154
* instead of migrating it to the MC instruction encoder, justChris Lattner2010-07-223-553/+100
| | | | | | | | | | | | | | rip out the implementation of X86InstrInfo::GetInstSizeInBytes. The code being ripped out just implemented a copy and hacked up version of the (old) instruction encoder, and is buggy and terrible in other ways. Since "GetInstSizeInBytes" is really only there to support the JIT's "NeedsExactSize" hook (which noone is using), just rip out the code. I will rip out the NeedsExactSize hook next. This resolves rdar://7617809 - switch X86InstrInfo::GetInstSizeInBytes to use X86MCCodeEmitter llvm-svn: 109149

* Add new RegionInfo pass.Tobias Grosser2010-07-223-0/+821
| | | | | | | | | | The RegionInfo pass detects single entry single exit regions in a function, where a region is defined as any subgraph that is connected to the remaining graph at only two spots. Furthermore an hierarchical region tree is built. Use it by calling "opt -regions analyze" or "opt -view-regions". llvm-svn: 109089
