Subject: [PATCH v2 2/2] ld: Support the -exclude-symbols option via COFF def files, with the EXCLUDE_SYMBOLS keyword
Date: Sat, 23 Jul 2022 01:02:03 +0300 [thread overview]
Message-ID: <20220722220203.1712670-2-martin@martin.st> (raw)
In-Reply-To: <20220722220203.1712670-1-martin@martin.st>
This was requested in review.

WIP: The testcase doesn't run successfully. How do I pass the
full path to exclude-symbols-def.def as parameter to the ld command?
