Pull in r200383 from upstream llvm trunk (by David Majnemer):
MC: Reorganize macro MC test along dialect lines
This commit seeks to do two things:
- Run the surfeit of tests under the Darwin dialect. This ends up
affecting tests which assumed that spaces could deliminate arguments.
- The GAS dialect tests should limit their surface area to things that
could plausibly work under GAS. For example, Darwin style arguments
have no business being in such a test.
Pull in r201784 from upstream llvm trunk (by Benjamin Kramer):
AsmParser: Disable Darwin-style macro argument expansion on non-darwin targets.
There is code in the wild that relies on $0 not being expanded.
This fixes some cases of using $ signs in literals being incorrectly
assembled.
