* Modify emission of jump tables on darwin to emit an extra "l" label thatEvan Cheng2007-01-191-0/+7
| | | | | | | delimits the boundaries of jump tables. This lets the linker's dead code stripping optimization do a better job. llvm-svn: 33362
* Remove this xform:Evan Cheng2007-01-191-7/+26
| | | | | | | | | | (shl (add x, c1), c2) -> (add (shl x, c2), c1<<c2) Replace it with: (add (shl (add x, c1), c2), ) -> (add (add (shl x, c2), c1<<c2), ) This fixes test/CodeGen/ARM/smul.ll llvm-svn: 33361

* - Target PIC style is no longer affected by relocation model.Evan Cheng2007-01-182-49/+49
| | | | | | | | - In x86-64 mode, symbols with external linkage (not just symbols which are defined externally) requires GOT indirect reference. - Stylistic code clean up. llvm-svn: 33345

* Clean up some code around the store V, (cast P) -> store (cast V), PReid Spencer2007-01-181-8/+14
| | | | | | | | | transform. Change some variable names so it is clear what is source and what is dest of the cast. Also, add an assert to ensure that the integer to integer case is asserting if the bitwidths are different. This prevents illegal casts from being formed and catches bitwidth bugs sooner. llvm-svn: 33337
* Use a cheaper computation.Reid Spencer2007-01-181-1/+1
| | | | llvm-svn: 33336
* Fix a regression in the last patch. When constructing a BitMask, be carefulReid Spencer2007-01-181-0/+4
| | | | | | | not to overflow 64-bits and end up with a 0 mask. This caused i64 values to always be stored as 0 with lots of consequential damage to nightly test. llvm-svn: 33335
* move contents of PR587 to here.Chris Lattner2007-01-181-0/+45

* Two changes:Reid Spencer2007-01-181-18/+17
| | | | | | | | | 1. Fix logic for executeGEP. Only 32-bit and 64-bit integer types are acceptable as indices. 2. Ensure that all integer cast operations truncate their result to the integer size of the operand. llvm-svn: 33318
* Make sure we truncate stored values to their bit width.Reid Spencer2007-01-181-30/+40

* For PR1028:Reid Spencer2007-01-171-2/+4
| | | | | | | | | | | | | Add the llvm.stacksave and llvm.stackrestore intrinsics that correspond to the GCC builtins __builtin_stack_save and __builtin_stack_restore. This allows the CBE to execute these builtins, and fixes: test/CodeGen/CBackend/2007-01-17-StackSaveNRestore.ll External/SPEC/CINT2000/176.gcc (CBE) Patch by Gordon Henriksen. llvm-svn: 33313
* For PR1028:Reid Spencer2007-01-171-0/+12
| | | | | | | | | Ensure the CBE generates calls to GCC builtins for stack_save and stack_restore when it encounters the corresponding intrinsics. Patch by Gordon Henriksen. llvm-svn: 33312

* For PR739:Reid Spencer2007-01-171-19/+13
| | | | | | | | | Support overriding the prefix and DESTDIR variables from the make command line. This makes the makefile system a little more GNU compliant and the feature makes it easier for distribution builders to re-target the install location of LLVM. llvm-svn: 33305
