* [ms-inline asm] Use parsePrimaryExpr in lieu of parseExpression if we need toChad Rosier2013-04-09
| | | | | | | | | | | | | | | parse an identifier. Otherwise, parseExpression may parse multiple tokens, which makes it impossible to properly compute an immediate displacement. An example of such a case is the source operand (i.e., [Symbol + ImmDisp]) in the below example: __asm mov eax, [Symbol + ImmDisp] The existing test cases exercise this patch. rdar://13611297 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179115 91177308-0d34-0410-b5e6-96231b3b80d8
* [ms-inline asm] Maintain a StringRef to reference a symbol in a parsed operand,Chad Rosier2013-04-09
| | | | | | | | | | | | | rather than deriving the StringRef from the Start and End SMLocs. Using the Start and End SMLocs works fine for operands such as [Symbol], but not for operands such as [Symbol + ImmDisp]. All existing test cases that reference a variable exercise this patch. rdar://13602265 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179109 91177308-0d34-0410-b5e6-96231b3b80d8

* [ms-inline asm] Add support for numeric displacement expressions in bracketedChad Rosier2013-04-05
| | | | | | | | | | | | | | | | | | | | | | | memory operands. Essentially, this layers an infix calculator on top of the parsing state machine. The scale on the index register is still expected to be an immediate __asm mov eax, [eax + ebx*4] and will not work with more complex expressions. For example, __asm mov eax, [eax + ebx*(2*2)] The plus and minus binary operators assume the numeric value of a register is zero so as to not change the displacement. Register operands should never be an operand for a multiply or divide operation; the scale*indexreg expression is always replaced with a zero on the operand stack to prevent such a case. rdar://13521380 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178881 91177308-0d34-0410-b5e6-96231b3b80d8
* [ms-inline asm] Add support for parsing variables with namespace aliasChad Rosier2013-04-02
| | | | | | | | | | | | | | qualifiers. This patch only adds support for parsing these identifiers in the X86AsmParser. The front-end interface isn't capable of looking up these identifiers at this point in time. The end result is the compiler now errors during object file emission, rather than at parse time.

* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | 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
