| | | | | | | doesn't support certain directives and symbols on cygwin are prefixed with an underscore. This patch makes the necessary adjustments to the output. llvm-svn: 19775

* If the interpreter tries to execute an external function, kill it. Of courseChris Lattner2005-01-211-6/+8
| | | | | | | | since we are dirty, special case __main. This should fix the infinite loop horrible stuff that happens on linux-alpha when configuring llvm-gcc. It might also help cygwin, who knows?? llvm-svn: 19729

| | | | | | | | | | | | | | | | | The second folds operations into selects, e.g. (select C, (X+Y), (Y+Z)) -> (Y+(select C, X, Z) This occurs a few times across spec, e.g. select add/sub mesa: 83 0 povray: 5 2 gcc 4 2 parser 0 22 perlbmk 13 30 twolf 0 3 llvm-svn: 19706

* Fix a problem where were were literally selecting for INCREASED registerChris Lattner2005-01-191-8/+8
| | | | | | | | pressure, not decreases register pressure. Fix problem where we accidentally swapped the operands of SHLD, which caused fourinarow to fail. This fixes fourinarow. llvm-svn: 19697
* Just in case, handle something that is both a use and a def.Chris Lattner2005-01-191-1/+2
| | | | llvm-svn: 19696
* When an instruction moves, make sure to update the VarInfo::Kills list asChris Lattner2005-01-191-3/+10
| | | | | | | well as all of teh other stuff in livevar. This fixes the compiler crash on fourinarow last night. llvm-svn: 19695
* When commuting these instructions, make sure to actually swap the operands too.Chris Lattner2005-01-191-1/+1
| | | | llvm-svn: 19694
* Fix 'raise' to work with packed types. Patch by Morten Ofstad.Chris Lattner2005-01-191-1/+1
| | | | llvm-svn: 19693
* Implement Regression/CodeGen/X86/rotate.ll: emit rotate instructions (whichChris Lattner2005-01-191-38/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | typically cost 1 cycle) instead of shld/shrd instruction (which are typically 6 or more cycles). This also saves code space. For example, instead of emitting: rotr: mov %EAX, DWORD PTR [%ESP + 4] mov %CL, BYTE PTR [%ESP + 8] shrd %EAX, %EAX, %CL ret rotli: mov %EAX, DWORD PTR [%ESP + 4] shrd %EAX, %EAX, 27 ret Emit: rotr32: mov %CL, BYTE PTR [%ESP + 8] mov %EAX, DWORD PTR [%ESP + 4] ror %EAX, %CL ret rotli32: mov %EAX, DWORD PTR [%ESP + 4] ror %EAX, 27 ret We also emit byte rotate instructions which do not have a sh[lr]d counterpart at all. llvm-svn: 19692
* Add rotate instructions.Chris Lattner2005-01-192-0/+75
| | | | llvm-svn: 19690
* Match 16-bit shld/shrd instructions as well, implementing shift-double.llx:test5Chris Lattner2005-01-191-16/+20
| | | | llvm-svn: 19689
* Improve coverage of the X86 instruction set by adding 16-bit shift doubles.Chris Lattner2005-01-193-3/+45
| | | | llvm-svn: 19687
* Teach the code generator that shrd/shld is commutable if it has an immediate.Chris Lattner2005-01-193-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | This allows us to generate this: foo: mov %EAX, DWORD PTR [%ESP + 4] mov %EDX, DWORD PTR [%ESP + 8] shld %EDX, %EDX, 2 shl %EAX, 2 ret instead of this: foo: mov %EAX, DWORD PTR [%ESP + 4] mov %ECX, DWORD PTR [%ESP + 8] mov %EDX, %EAX shrd %EDX, %ECX, 30 shl %EAX, 2 ret Note the magically transmogrifying immediate. llvm-svn: 19686
* Use the TargetInstrInfo::commuteInstruction method to commute instructionsChris Lattner2005-01-191-6/+17
| | | | | | instead of doing it manually. llvm-svn: 19685
* Finegrainify namespacificationChris Lattner2005-01-191-7/+20
| | | | | | | Add default impl of commuteInstruction Add notes about ugly V9 code. llvm-svn: 19684
