Subject: MCDwarfLineTableheader::tryGetFile : replace a loop with llvm::find
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=77dd066466e0e9bd4965e06497891e42dab27597;p=llvm

MCDwarfLineTableheader::tryGetFile : replace a loop with llvm::find

Note, `DirIndex++` below is incorrect for DWARF 5, but it can be fixed
later after the file index is fixed.
