Subject: COFF: Add support for Dwarf accelerator tables.
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3f1a0a7ce274f0f59493e31013afceb93f8a3764;p=platform%2Fupstream%2Fllvm.git

COFF: Add support for Dwarf accelerator tables.

This allows COFF targets to emit accelerator tables
when requested by -dwarf-accel-tables=Enable instead
of aborting. The test DebugInfo/cross-cu-inlining.ll
covers this on COFF platforms.
