[PowerPC] Temporarily disable VSX for PowerPC fast-isel tests Patch by Bill Seurer; some comment formatting changes by me. There are a few PowerPC test cases for FastISel support that currently fail with VSX support enabled. The temporary workaround under discussion in http://reviews.llvm.org/D5362 helps, but the tests still fail because they specify -fast-isel-abort, and the VSX workaround punts back to SelectionDAG. We have plans to fix FastISel permanently for VSX, but until that's in place these tests are preventing us from enabling VSX by default. Therefore we are adding -mattr=-vsx to these tests until the full support is ready. llvm-svn: 220172

; FIXME: FastISel currently returns false if it hits code that uses VSX
Change the fast-isel-abort option from bool to int to enable "levels" Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

[PowerPC] More fast-isel chunks (returns and integer extends) Incremental improvement to fast-isel for PPC64. This allows us to select on ret, sext, and zext. Filling in sext/zext improves some of the existing logic in handling compare-immediates that needed extends. A simplified return convention for fast-isel is also added to the PPC64 calling conventions. All call/return processing for DAG selection is handled with custom code, so there isn't an existing CC to rely on here. The include of PPCGenCallingConv.inc causes compiler warnings due to the 32-bit calling conventions that are not used, so the dummy function "usePPC32CCs()" is added here to silence those. Test cases for the return and extend logic are added. llvm-svn: 189266

Fix FastISel bug in boolean returns for PowerPC. For PPC targets, FastISel does not take the sign extension information into account when selecting return instructions whose operands are constants. A consequence of this is that the return of boolean values is not correct. This patch fixes the problem by evaluating the sign extension information also for constants, forwarding this information to PPCMaterializeInt which takes this information to drive the sign extension during the materialization. llvm-svn: 217993

[PowerPC] More fast-isel chunks (returns and integer extends) Incremental improvement to fast-isel for PPC64. This allows us to select on ret, sext, and zext. Filling in sext/zext improves some of the existing logic in handling compare-immediates that needed extends. A simplified return convention for fast-isel is also added to the PPC64 calling conventions. All call/return processing for DAG selection is handled with custom code, so there isn't an existing CC to rely on here. The include of PPCGenCallingConv.inc causes compiler warnings due to the 32-bit calling conventions that are not used, so the dummy function "usePPC32CCs()" is added here to silence those.

Fix FastISel bug in boolean returns for PowerPC. For PPC targets, FastISel does not take the sign extension information into account when selecting return instructions whose operands are constants. A consequence of this is that the return of boolean values is not correct. This patch fixes the problem by evaluating the sign extension information also for constants, forwarding this information to PPCMaterializeInt which takes this information to drive the sign extension during the materialization. llvm-svn: 217993
