| | | | | | | | | | override prefix and only the r/m16 forms should have had that. Also for variant one, the AT&T syntax, added suffixes to all forms. Also added the missing 64-bit form for 'CRC32 r64, r/m8'. Plus added test cases for all forms and tweaked one test case to add the needed suffixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98980 91177308-0d34-0410-b5e6-96231b3b80d8
* Stop trying to merge identical jump tables. This had been inadvertentlyBob Wilson2010-03-192-39/+6
| | | | | | | | | | | | disabled for several months (since svn r88806) and no one noticed. My fix for pr6543 yesterday reenabled it, but broke the ARM port's code for using TBB/TBH. Rather than adding a target hook to disable merging for Thumb2 only, I'm just taking this out. It is not common to have identical jump tables, the code we used to merge them was O(N^2), and it only helps code size, not performance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98977 91177308-0d34-0410-b5e6-96231b3b80d8
* MC/Mach-O/x86_64: Add relocation support.Daniel Dunbar2010-03-191-0/+213
| | | | | | | | - This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information. - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily). - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98974 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | This time I did a self-hosted bootstrap on Linux x86-64, with no problems. Let's see how darwin 64-bit self-hosting goes. At the first sign of failure I'll back this out.

* Now that tblgen can handle matching implicit defs of instructionsChris Lattner2010-03-194-131/+104
| | | | | | | | | | | | | | | | | | | | | | | | | | | to input patterns, we can fix X86ISD::CMP and X86ISD::BT as taking two inputs (which have to be the same type) and *returning an i32*. This is how the SDNodes get made in the graph, but we weren't able to model it this way due to deficiencies in the pattern language. Now we can change things like this: def UCOM_FpIr80: FpI_<(outs), (ins RFP80:$lhs, RFP80:$rhs), CompareFP, - [(X86cmp RFP80:$lhs, RFP80:$rhs), - (implicit EFLAGS)]>; // CC = ST(0) cmp ST(i) + [(set EFLAGS, (X86cmp RFP80:$lhs, RFP80:$rhs))]>; and fix terrible crimes like this: -def : Pat<(parallel (X86cmp GR8:$src1, 0), (implicit EFLAGS)), +def : Pat<(X86cmp GR8:$src1, 0), (TEST8rr GR8:$src1, GR8:$src1)>; This relies on matching the result of TEST8rr (which is EFLAGS, which is an implicit def) to the result of X86cmp, an i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98903 91177308-0d34-0410-b5e6-96231b3b80d8
