[PATCH] D64651: [Driver] Support file paths with -ccc-gcc-name

2019-07-12 Thread Alex James via Phabricator via cfe-commits 
al3xtjames created this revision.
al3xtjames added a reviewer: llvm-commits.
Herald added a project: clang.
Herald added a subscriber: cfe-commits.

When a file path is specified for gcc-name, don't prepend the target
triple. This allows -target and -ccc-gcc-name to be used together when
a file path is used.

[PATCH] D61838: [Sema] Suppress additional warnings for C's zero initializer

2019-05-12 Thread Alex James via Phabricator via cfe-commits 
al3xtjames created this revision.
al3xtjames added a reviewer: cfe-commits.
Herald added a project: clang.

r314499 relaxed some checks for assigning { 0 } to a structure for all
C standards, but it failed to handle structures with non-integer
subobjects. Relax -Wmissing-braces checks for such structures, and add
some additional tests.

This fixes PR39931.
