LLVM with the emscripten fastcomp javascript backend https://git.amat.us/emscripten-fastcomp/atom/lib/Target/PowerPC/Makefile?h=master 2013-05-03T19:49:39Z 2013-05-03T19:49:39Z Ulrich Weigand ulrich.weigand@de.ibm.com 2013-05-03T19:49:39Z urn:sha1:5e220753ff81ac5cbee874e7c00c76c7fbe0d20a This adds assembler parser support to the PowerPC back end. The parser will run for any powerpc-*-* and powerpc64-*-* triples, but was tested only on 64-bit Linux. The supported syntax is intended to be compatible with the GNU assembler. The parser does not yet support all PowerPC instructions, but it does support anything that is generated by LLVM itself. There is no support for testing restricted instruction sets yet, i.e. the parser will always accept any instructions it knows, no matter what feature flags are given. Instruction operands will be checked for validity and errors generated. (Error handling in general could still be improved.) The patch adds a number of test cases to verify instruction and operand encodings. The tests currently cover all instructions from the following PowerPC ISA v2.06 Book I facilities: Branch, Fixed-point, Floating-Point, and Vector. Note that a number of these instructions are not yet supported by the back end; they are marked with FIXME. A number of follow-on check-ins will add extra features. When they are all included, LLVM passes all tests (including bootstrap) when using clang -cc1as as the system assembler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181050 91177308-0d34-0410-b5e6-96231b3b80d8 2011-07-14T20:59:42Z Evan Cheng evan.cheng@apple.com 2011-07-14T20:59:42Z urn:sha1:c60f9b752381baa6c4b80c0739034660f1748c84 registeration and creation code into XXXMCDesc libraries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135184 91177308-0d34-0410-b5e6-96231b3b80d8 2011-07-01T22:36:09Z Evan Cheng evan.cheng@apple.com 2011-07-01T22:36:09Z urn:sha1:385e930d55f3ecd3c9538823dfa5896a12461845 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134281 91177308-0d34-0410-b5e6-96231b3b80d8 2011-06-28T20:07:07Z Evan Cheng evan.cheng@apple.com 2011-06-28T20:07:07Z urn:sha1:22fee2dff4c43b551aefa44a96ca74fcade6bfac git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@134024 91177308-0d34-0410-b5e6-96231b3b80d8 2011-06-27T18:32:37Z Evan Cheng evan.cheng@apple.com 2011-06-27T18:32:37Z urn:sha1:73f50d9bc3bd46cc0abeba9bb0d46977ba1aea42 into XXXGenRegisterInfo.inc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133922 91177308-0d34-0410-b5e6-96231b3b80d8 2011-06-24T01:44:41Z Evan Cheng evan.cheng@apple.com 2011-06-24T01:44:41Z urn:sha1:a347f85dbeee37a7f2bb68df1a7d4cdfbb7b576d target machine from those that are only needed by codegen. The goal is to sink the essential target description into MC layer so we can start building MC based tools without needing to link in the entire codegen. First step is to refactor TargetRegisterInfo. This patch added a base class MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to separate register description from the rest of the stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133782 91177308-0d34-0410-b5e6-96231b3b80d8 2010-11-15T04:16:32Z Chris Lattner sabre@nondot.org 2010-11-15T04:16:32Z urn:sha1:5ffe38ef6ae3427b39b2d866ab8d1a73f9f69e56 fixups yet, and doesn't handle actually encoding operand values, but this is enough for llc -show-mc-encoding to show the base instruction encoding information, e.g.: mflr r0 ; encoding: [0x7c,0x08,0x02,0xa6] stw r0, 8(r1) ; encoding: [0x90,0x00,0x00,0x00] stwu r1, -64(r1) ; encoding: [0x94,0x00,0x00,0x00] Ltmp0: lhz r4, 4(r3) ; encoding: [0xa0,0x00,0x00,0x00] cmplwi cr0, r4, 8 ; encoding: [0x28,0x00,0x00,0x00] beq cr0, LBB0_2 ; encoding: [0x40,0x00,0x00,0x00] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119116 91177308-0d34-0410-b5e6-96231b3b80d8 2010-11-14T19:40:38Z Chris Lattner sabre@nondot.org 2010-11-14T19:40:38Z urn:sha1:60d5b5fdeec64b69c92db60242d3d90b3f978e69 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119059 91177308-0d34-0410-b5e6-96231b3b80d8 2010-11-14T18:33:33Z Chris Lattner sabre@nondot.org 2010-11-14T18:33:33Z urn:sha1:0094345184bc0a791f0811c8d7f5b6f9c8296e0f git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119054 91177308-0d34-0410-b5e6-96231b3b80d8 2010-01-24T20:43:08Z Chris Lattner sabre@nondot.org 2010-01-24T20:43:08Z urn:sha1:43b5f9312d56be400af031f7487a99b75b7b0f97 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94378 91177308-0d34-0410-b5e6-96231b3b80d8
