Subject: [PATCH v2 20/21] libcc1: avoid extra string copies
Date: Tue, 27 Apr 2021 19:01:18 -0600 [thread overview]
Message-ID: <20210428010119.806184-21-tom@tromey.com> (raw)
In-Reply-To: <20210428010119.806184-1-tom@tromey.com>
PR c/94669 points out that a couple of spots in libcc1 take a
std::string where a reference would do. This changes these spots to
take a const char *, to reduce the number of copies.

PR c/94669:
* compiler.hh (compiler_driver_filename): Take const char *.
(compiler_triplet_regexp): Likewise.
