2013-05-03[PowerPC] Avoid using '$' in generated assembler codeUlrich Weigand
PowerPC assemblers are supposed to support a stand-alone '$' symbol as an alternative of '.' to refer to the current PC. This does not work in the LLVM assembler parser yet. To avoid bootstrap failures when using the LLVM assembler as system assembler, this patch modifies the assembler source code generated by LLVM to avoid using '$' (and simply use '.' instead). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181054 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26PPC: Use HWEncoding and TRI->getEncodingValueHal Finkel
As pointed out by Jakob, we don't need to maintain a separate register-numbering table. Instead we should let TableGen generate the table for us from the information (already present) in PPCRegisterInfo.td. TRI->getEncodingValue is now used to access register-encoding values. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178067 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26PowerPC: Use CCBITRC operand for ISEL patterns.Ulrich Weigand
This commit changes the ISEL patterns to use a CCBITRC operand instead of a "pred" operand. This matches the actual instruction text more directly, and simplifies use of ISEL with the asm parser. In addition, this change allows some simplification of handling the "pred" operand, as this is now only used by BCC. No change in generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178003 91177308-0d34-0410-b5e6-96231b3b80d8
2013-03-26PowerPC: Simplify BLR pattern.Ulrich Weigand
The BLR pattern cannot be recognized by the asm parser in its current form. This complexity is due to an apparent attempt to enable conditional BLR variants. However, none of those can ever be generated by current code; the pattern is only ever created using the default "pred" operand. To simplify the pattern and allow it to be recognized by the parser, this commit removes those attempts at conditional BLR support. When we later come back to actually add real conditional BLR, this should probably be done via a fully generic conditional branch pattern. No change in generated code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178002 91177308-0d34-0410-b5e6-96231b3b80d8
2012-10-08PR12716: PPC crashes on vector compareAdhemerval Zanella
Vector compare using altivec 'vcmpxxx' instructions have as third argument a vector register instead of CR one, different from integer and float-point compares. This leads to a failure in code generation, where 'SelectSETCC' expects a DAG with a CR register and gets vector register instead. This patch changes the behavior by just returning a DAG with the vector compare instruction based on the type. The patch also adds a testcase for all vector types llvm defines. It also included a fix on signed 5-bits predicates printing, where signed values were not handled correctly as signed (char are unsigned by default for PowerPC). This generates 'vspltisw' (vector splat) instruction with SIM out of range. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165419 91177308-0d34-0410-b5e6-96231b3b80d8
