| unsigned TargetAsmInfo::getInlineAsmLength | ( | const char * | Str | ) | const [virtual] |
Measure the specified inline asm to determine an approximation of its length.
Measure the specified inline asm to determine an approximation of its length. Comments (which run till the next SeparatorChar or newline) do not count as an instruction. Any other non-whitespace text is considered an instruction, with multiple instructions separated by SeparatorChar or newlines. Variable-length instructions are not handled here; this function may be overloaded in the target code to do that.

| virtual bool llvm::TargetAsmInfo::ExpandInlineAsm | ( | CallInst * | CI | ) | const [inline, virtual] |
ExpandInlineAsm - This hook allows the target to expand an inline asm call to be explicit llvm code if it wants to. This is useful for turning simple inline asms into LLVM intrinsics, which gives the compiler more information about the behavior of the code.
Reimplemented in llvm::X86TargetAsmInfo< llvm::DarwinTargetAsmInfo >, llvm::X86TargetAsmInfo< llvm::ELFTargetAsmInfo >, and llvm::X86TargetAsmInfo< llvm::TargetAsmInfo >.

| virtual bool llvm::TargetAsmInfo::emitUsedDirectiveFor | ( | const GlobalValue * | GV, | |

emitUsedDirectiveFor - This hook allows targets to selectively decide not to emit the UsedDirective for some symbols in llvm.used.

| unsigned TargetAsmInfo::PreferredEHDataFormat | ( | DwarfEncoding::Target | Reason, | |
| bool | Global | |||
| ) | const [virtual] |
PreferredEHDataFormat - This hook allows the target to select data format used for encoding pointers in exception handling data. Reason is 0 for data, 1 for code labels, 2 for function pointers. Global is true if the symbol can be relocated.
