Support ppc64 implemented and half tested (passes my tests). On ppc tail call optimization is performed if caller and callee are fastcc call is a tail call (in tail call position, call followed by ret) no variable argument lists or byval arguments option -tailcallopt is enabled Supported: * non pic tail calls on linux/darwin * module-local tail calls on linux(PIC/GOT)/darwin(PIC) * inter-module tail calls on darwin(PIC) If constraints are not met a normal call will be emitted. A test checking the argument lowering behaviour on x86-64 was added. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50477 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-27T00:37:18Z Chris Lattner sabre@nondot.org 2008-04-27T00:37:18Z urn:sha1:5a09690446a36f94f990db7d18d9b9ac8587888a When choosing between constraints with multiple options, like "ir", test to see if we can use the 'i' constraint and go with that if possible. This produces more optimal ASM in all cases (sparing a register and an instruction to load it), and fixes inline asm like this: void test () { asm volatile (" %c0 %1 " : : "imr" (42), "imr"(14)); } Previously we would dump "42" into a memory location (which is ok for the 'm' constraint) which would cause a problem because the 'c' modifier is not valid on memory operands. Isn't it great how inline asm turns 'missed optimization' into 'compile failed'?? Incidentally, this was the todo in PowerPC/2007-04-24-InlineAsm-I-Modifier.ll Please do NOT pull this into Tak. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50315 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-24T20:01:58Z Evan Cheng evan.cheng@apple.com 2008-04-24T20:01:58Z urn:sha1:1e8586d175872bd7372cad52e97660f2c3fcc8de git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50229 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-19T02:30:38Z Evan Cheng evan.cheng@apple.com 2008-04-19T02:30:38Z urn:sha1:8608f2eff2dab5345243c40d0bca9138f2dce6f1 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49949 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-16T20:24:25Z Evan Cheng evan.cheng@apple.com 2008-04-16T20:24:25Z urn:sha1:9c1e06e18721206c736512f3448997b41145019c git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49810 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-14T17:56:54Z Dale Johannesen dalej@apple.com 2008-04-14T17:56:54Z urn:sha1:0a6ee6d1316831c3a5e5e3e0a229eb269795891a this is now the default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49667 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-10T18:38:47Z Evan Cheng evan.cheng@apple.com 2008-04-10T18:38:47Z urn:sha1:172b70c62a315de654a4d1683dbb5544e67afa90 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49491 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-08T18:10:08Z Dale Johannesen dalej@apple.com 2008-04-08T18:10:08Z urn:sha1:c8abfdec84c86d32a84d71d3f476a54f162afbcc git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49391 91177308-0d34-0410-b5e6-96231b3b80d8 2008-04-08T00:14:59Z Dale Johannesen dalej@apple.com 2008-04-08T00:14:59Z urn:sha1:a25e5787bc3a56fbc8983dfe6be68e00cd1709b4 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@49365 91177308-0d34-0410-b5e6-96231b3b80d8
