◆ AnalyzeAsmString()

unsigned GCCAsmStmt::AnalyzeAsmString ( SmallVectorImpl< AsmStringPiece > &  Pieces,
const ASTContext C,
unsigned &  DiagOffs

AnalyzeAsmString - Analyze the asm string of the current asm, decomposing it into pieces.

If the asm string is erroneous, emit errors and return true, otherwise return false. This handles canonicalization and translation of strings from GCC syntax to LLVM IR syntax, and handles

If the asm string is erroneous, emit errors and return true, otherwise return false.
