* [ms-inline asm] Asm operands can map to one or more MCOperands. Therefore, addChad Rosier2012-09-034-8/+11
| | | | | | | the NumMCOperands argument to the GetMCInstOperandNum() function that is set to the number of MCOperands this asm operand mapped to. llvm-svn: 163124

* Fix more fallout from r158919, similar to PR13547.Bob Wilson2012-09-031-2/+7
| | | | | | | | | This code used to only handle malloc-like calls, which do not read memory. r158919 changed it to check isNoAliasFn(), which includes strdup-like and realloc-like calls, but it was not checking for dependencies on the memory read by those calls. llvm-svn: 163106
* Removed unused argument.Chad Rosier2012-09-033-18/+15

| | | | | | | | | | MatchInstructionImpl() function. These values are used by the ConvertToMCInst() function to index into the ConversionTable. The values are also needed to call the GetMCInstOperandNum() function. llvm-svn: 163101

| | | | llvm-svn: 163094
* Not all targets have efficient ISel code generation for select instructions.Nadav Rotem2012-09-022-7/+27
| | | | | | | | | For example, the ARM target does not have efficient ISel handling for vector selects with scalar conditions. This patch adds a TLI hook which allows the different targets to report which selects are supported well and which selects should be converted to CF duting codegen prepare. llvm-svn: 163093
* LoopRotation: Make the brute force DomTree update more brute force.Benjamin Kramer2012-09-021-32/+21
| | | | | | | | | | | | | | We update until we hit a fixpoint. This is probably slow but also slightly simplifies the code. It should also fix the occasional invalid domtrees observed when building with expensive checking. I couldn't find a case where this had a measurable slowdown, but if someone finds a pathological case where it does we may have to find a cleverer way of updating dominators here. Thanks to Duncan for the test case. llvm-svn: 163091
* Rename ANDROIDEABI to Android.Logan Chien2012-09-022-3/+3
| | | | | | | | | | | | | Most of the code guarded with ANDROIDEABI are not ARM-specific, and having no relation with arm-eabi. Thus, it will be more natural to call this environment "Android" instead of "ANDROIDEABI". Note: We are not using ANDROID because several projects are using "-DANDROID" as the conditional compilation flag. llvm-svn: 163087

| | | | | | | | | zeros or all ones. A vector bool with just ones isn't suitable for masking with. No test case unfortunately as i couldn't find a target which fit all the conditions needed to hit this code. llvm-svn: 163075
* Limit domain conversion to cases where it won't break dep chains.Tim Northover2012-09-011-12/+48
| | | | | | | | NEON domain conversion was too heavy-handed with its widened registers, which could have stripped existing instructions of their dependency, leaving them vulnerable to scheduling errors. llvm-svn: 163070

| | | | | | | | | | | Manage tied operands entirely internally to MachineInstr. This makes it possible to change the representation of tied operands, as I will do shortly. The constraint that tied uses and defs must be in the same order was too restrictive. llvm-svn: 163021
