MCParser: diagnose missing directional labels more clearly. Before, ELF at least managed a diagnostic but it was a completely untraceable "undefined symbol" error. MachO had a variety of even worse behaviours: crash, emit corrupt file, or an equally bad message. llvm-svn: 265984 2016-04-11 21:50:46 +02:00			`// RUN: not llvm-mc -triple x86_64-linux-gnu -filetype=obj -o /dev/null %s 2>&1 \| FileCheck %s`

AsmParser: record "# line file" context to calculate location for diag Since we can't emit diagnostics for missing "jmp 1f" labels until the end of the file, we need to be able to restore the context used to calculate file/line. This is basically the "# line file" directive that's being used at the time the expression is seen. rdar://25706972 llvm-svn: 266238 2016-04-13 21:46:54 +02:00			`# 10 "wibble.s"`
