2013-03-27[ms-inline asm] Add support of imm displacement before bracketed memoryChad Rosier

2013-03-19[ms-inline asm] Move the immediate asm rewrite into the target specificChad Rosier

2013-03-19[ms-inline asm] Create a helper function, CreateMemForInlineAsm, that createsChad Rosier
an X86Operand, but also performs a Sema lookup and adds the sizing directive when appropriate. Use this when parsing a bracketed statement. This is necessary to get the instruction matching correct as well.

2013-01-07Change SMRange to be half-open (exclusive end) instead of closed (inclusive)Jordan Rose
This is necessary not only for representing empty ranges, but for handling multibyte characters in the input. (If the end pointer in a range refers to a multibyte character, should it point to the beginning or the end of the character in a char array?) Some of the code in the asm parsers was already assuming this anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171765 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-24[ms-inline asm] Create a register operand, rather than a memory operand when weChad Rosier
see the offsetof operator. Previously, we were matching something like MOVrm in the front-end and later matching MOVrr in the back-end. This change makes things more consistent.

2012-10-23[ms-inline asm] When parsing inline assembly we set the base register to aChad Rosier
non-zero value as we don't know the actual value at this point. This is necessary to get the matching correct in some cases. However, the actual value set as the base register doesn't matter, since we're just matching not emitting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166523 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-13[ms-inline asm] Remove the MatchInstruction() function. Previously, this wasChad Rosier
the interface between the front-end and the MC layer when parsing inline assembly. Unfortunately, this is too deep into the parsing stack. Specifically, we're unable to handle target-independent assembly (i.e., assembly directives, labels, etc.). Note the MatchAndEmitInstruction() isn't the correct abstraction either. I'll be exposing target-independent hooks shortly, so this is really just a cleanup. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165858 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-02[ms-inline asm] Add basic support for wildcard MCParsedAsmOperands. This typeChad Rosier
of operand is specific to MS-style inline assembly and should not be generated when parsing normal assembly. The purpose of the wildcard operands are to allow the AsmParser to match multiple instructions (i.e., MCInsts) to a given ms-style asm statement. For the time being the matcher just returns the first match. This patch only implements wildcard matches for memory operands. Support for register wildcards will be added in the near future. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165057 91177308-0d34-0410-b5e6-96231b3b80d8
