[ThinLTO] Serialize WithGlobalValueDeadStripping index flag for distributed backends 2018-02-07T04:05:59+00:00 Teresa Johnson tejohnson@google.com 2018-02-07T04:05:59+00:00 f3681015670c531cb42bc20dbbe78cb237b055d7 Summary: A recent fix to drop dead symbols (r323633) did not work for ThinLTO distributed backends because we lose the WithGlobalValueDeadStripping set on the index during the thin link. This patch adds a new flags record to the bitcode format for the index, and serializes this flag for the combined index (it would always be 0 for the per-module index generated by the compile step, so no need to serialize the new flags record there until/unless we add another flag that applies to the per-module indexes). Generally this flag should always be set for the distributed backends, which are necessarily performed after the thin link. However, if we were to simply set this flag on the index applied to the distributed backends (invoked via clang), we would lose the ability to disable dead stripping via -compute-dead=false for debugging purposes.

Summary:
A recent fix to drop dead symbols (r323633) did not work for ThinLTO
distributed backends because we lose the WithGlobalValueDeadStripping
set on the index during the thin link. This patch adds a new flags
record to the bitcode format for the index, and serializes this flag
for the combined index (it would always be 0 for the per-module index
generated by the compile step, so no need to serialize the new flags
record there until/unless we add another flag that applies to the
per-module indexes).

Generally this flag should always be set for the distributed backends,
which are necessarily performed after the thin link. However, if we were
to simply set this flag on the index applied to the distributed backends
(invoked via clang), we would lose the ability to disable dead stripping
via -compute-dead=false for debugging purposes.
