[PowerPC] Add some Book II instructions to AsmParser This patch adds a couple of Book II instructions (isync, icbi) to the PowerPC assembler parser. These are needed when bootstrapping clang with the integrated assembler forced on, because they are used in inline asm statements in the code base. The test case adds the full list of Book II storage control instructions, including associated extended mnemonics. Again, those that are not yet supported as marked as FIXME. llvm-svn: 181052

[PowerPC] Generate little-endian object files As a first step towards real little-endian code generation, this patch changes the PowerPC MC layer to actually generate little-endian object files. This involves passing the little-endian flag through the various layers, including down to createELFObjectWriter so we actually get basic little-endian ELF objects, emitting instructions in little-endian order, and handling fixups and relocations as appropriate for little-endian. The bulk of the patch is to update most test cases in test/MC/PowerPC to verify both big- and little-endian encodings. (The only test cases *not* updated are those that create actual big-endian ABI code, like the TLS tests.) Note that while the object files are now little-endian, the generated code itself is not yet updated, in particular, it still does not adhere to the ELFv2 ABI. llvm-svn: 204634

[PowerPC] Add support for dcbtst and icbt (prefetch) Adds code generation support for dcbtst (data cache prefetch for write) and icbt (instruction cache prefetch for read - Book E cores only). We still end up with a 'cannot select' error for the non-supported prefetch intrinsic forms. This will be fixed in a later commit. Fixes PR20692. llvm-svn: 216339

[PowerPC] Add asm/disasm support for dcbt with hint Add assembler/disassembler support for dcbt/dcbtst (and aliases) with the hint field specified (non-zero). Unforunately, the syntax for this instruction is special in that it differs for server vs. embedded cores: dcbt ra, rb, th [server] dcbt th, ra, rb [embedded] where th can be omitted when it is 0. dcbtst is the same. Thus we need to play games in the parser and the printer to flip the operands around on the embedded cores. We'll use the server syntax as the default (binutils currently uses the embedded form by default, but IBM is changing that). We also stop marking dcbtst as having unmodeled side effects (this is not necessary, it is just a hint like dcbt -- noticed by inspection, so no separate test case). llvm-svn: 235657

The bulk of the patch is to update most test cases in test/MC/PowerPC to verify both big- and little-endian encodings. (The only test cases *not* updated are those that create actual big-endian ABI code, like the TLS tests.) Note that while the object files are now little-endian, the generated code itself is not yet updated, in particular, it still does not adhere to the ELFv2 ABI. llvm-svn: 204634

[PowerPC] Enable printing instructions using aliases TableGen had been nicely generating code to print a number of instructions using shorter aliases (and PowerPC has plenty of short mnemonics), but we were not calling it. For some of the aliases we support in the parser, TableGen can't infer the "inverse" alias relationship, so there is still more to do. Thus, after some hours of updating test cases... llvm-svn: 235616

[PowerPC] Generate little-endian object files As a first step towards real little-endian code generation, this patch changes the PowerPC MC layer to actually generate little-endian object files. This involves passing the little-endian flag through the various layers, including down to createELFObjectWriter so we actually get basic little-endian ELF objects, emitting instructions in little-endian order, and handling fixups and relocations as appropriate for little-endian. The bulk of the patch is to update most test cases in test/MC/PowerPC to verify both big- and little-endian encodings. (The only test cases *not* updated are those that create actual big-endian ABI code, like the TLS tests.)

[PowerPC] Add some Book II instructions to AsmParser This patch adds a couple of Book II instructions (isync, icbi) to the PowerPC assembler parser. These are needed when bootstrapping clang with the integrated assembler forced on, because they are used in inline asm statements in the code base. The test case adds the full list of Book II storage control instructions, including associated extended mnemonics. Again, those that are not yet supported as marked as FIXME. llvm-svn: 181052
