2010-05-18Incorporate Daniel's suggestion and use !isdigit(CurPtr[0]) and notKevin Enderby
CurPtr[0] == '\n' when testing the character after a "0b" when looking to see if it part of a something like "jmp 0b". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104039 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-18Fixed the problem with a branch to "0b" that was not parsed by llvm-mcKevin Enderby
correctly. The Lexer was incorrectly eating the newline casusing it to branch to address 0. Updated the test case to use a "0:" label and a branch to "0b". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@104038 91177308-0d34-0410-b5e6-96231b3b80d8

sections, not all sections in the text segment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103981 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-17llvm-mc: Support reassignment of variables in one special case, when theDaniel Dunbar
variable has not yet been used in an expression. This allows us to support a few cases that show up in real code (mostly because gcc generates it for Objective-C on Darwin), without giving up a reasonable semantic model for assignment. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103950 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-13fix rdar://7965971 and a fixme: use ParseIdentifier inChris Lattner

2010-03-30Rip out the 'is temporary' nonsense from the MCContext interface toChris Lattner
create symbols. It is extremely error prone and a source of a lot of the remaining integrated assembler bugs on x86-64. This fixes rdar://7807601. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99902 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-15MC: Allow modifiers in MCSymbolRefExpr, and eliminate X86MCTargetExpr.Daniel Dunbar
- Although it would be nice to allow this decoupling, the assembler needs to be able to reason about MCSymbolRefExprs in too many places to make this viable. We can use a target specific encoding of the variant if this becomes an issue. - This patch also extends llvm-mc to support parsing of the modifiers, as opposed to lumping them in with the symbol. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98592 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22Stop building RTTI information for *most* llvm libraries. NotableChris Lattner
missing ones are libsupport, libsystem and libvmcore. libvmcore is currently blocked on bugpoint, which uses EH. Once it stops using EH, we can switch it off. This #if 0's out 3 unit tests, because gtest requires RTTI information. Suggestions welcome on how to fix this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94164 91177308-0d34-0410-b5e6-96231b3b80d8
