2011-12-02Add support for AVX registers to clang inline asm. Add a small testcaseEric Christopher
and update the Sema testcase with a register that we won't hit for a while I hope. Fixes rdar://10510405 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145671 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-29Fix assertion failure in CodeGen where the input operand to an asmPeter Collingbourne
instruction is tied to an output operand which is a pointer, and the input operand is narrower than the output operand. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136438 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-23fix PR10415, tidying up IR representation of module level inline asmChris Lattner
to avoid extraneous \n's. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135862 91177308-0d34-0410-b5e6-96231b3b80d8

extra register. Part of PR10299 and rdar://9740322 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134657 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24Add some missing X86-specific asm constraint letters, and fixDale Johannesen
some bugs in setting allowsRegister on the ones there. 8348447. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111980 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-23Implement PR6845. We allow matching constraints to have differentChris Lattner
input and output types when the smaller value isn't mentioned in the asm string. Extend this support from integers to also allowing fp values to be mismatched (if not mentioned in the asm string). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@102188 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-05fix PR6780, properly handling the IR {|} escapes in inline asm strings.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100449 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-04fix a buildbot failure, this was passing for me because the Chris Lattner
'%t' file was left around on my disk. doh. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97699 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-03merge asm-2.c into asm.c, remove asm-inout.c because it is Chris Lattner
XFAIL and already tracked in bugzilla. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97671 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-03fix PR6475, we were doing side-effecting stuff in an assert.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@97669 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-15Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.Daniel Dunbar
- This is designed to make it obvious that %clang_cc1 is a "test variable" which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it can be useful to redefine what gets run as 'clang -cc1' (for example, to set a default target). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91446 91177308-0d34-0410-b5e6-96231b3b80d8

- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86430 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13fix PR4938 by recognizing % as a modifier on outputs,Chris Lattner
previously we only recognized it on inputs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@83939 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-25MultiTestRunner: Validate '&&' at the end of RUN lines.Daniel Dunbar
- This is just to normalize, these will go away soon hopefully. Added all the missing '&&'s that have crept in. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@77062 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-03allow references to the larger value in a tied constraintChris Lattner
from the asm string, but reject references to the smaller one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70679 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-03add support for tying asm operands where the result is smaller thanChris Lattner
the input. This is part of PR3373. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70677 91177308-0d34-0410-b5e6-96231b3b80d8

2009-05-03implement support for asm outputs targetting non-simple lvalue destinationsChris Lattner
like bitfields. incidentally llvm-gcc crashes on this sort of thing also. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70675 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-03Ignore plus operands when looking up the operand number from a named ↵Anders Carlsson
operand. This matches llvm-gcc and fixes PR3908. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68371 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-24Rename clang to clang-cc.Daniel Dunbar
Tests and drivers updated, still need to shuffle dirs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@67602 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-10Fix PR3682 by just disabling a broken assertion. This check should beChris Lattner
done in sema, and is reflected by the existing PR3258. In the meantime, fix PR3682 by disabling a bogus assertion (which doesn't account for + operands). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66533 91177308-0d34-0410-b5e6-96231b3b80d8

time handle + operands in operand counting, fixing asm.c:t7 to expand into $2 instead of $1. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@66531 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-27If an input constraint refers to an output constraint, it should have the ↵Anders Carlsson
same constraint info as the output constraint. Fixes PR3417 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@63127 91177308-0d34-0410-b5e6-96231b3b80d8
