Subject: [Driver][test] Avoid undefined grep in darwin-ld.c
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=0165340d205499f0904110b90f4ec1df5657a8c6;p=clang

[Driver][test] Avoid undefined grep in darwin-ld.c

Summary:
question-mark is not a BRE special character.

POSIX.1-2017 XBD Section 9.3.2 indicates that the interpretation of `\?`
as used by rC366282 is undefined. This patch uses an ERE instead.
