We leave the following ones unchanged: - geckodriver because the results are used to releases on github. - sixgill because the script that creates it is not in-tree. - *-dist-toolchain because sccache is not expecting a .tar.zst. We use native tar support in most cases, except for toolchain scripts also used on Windows, for which we use our zstdpy script. Differential Revision: https://phabricator.services.mozilla.com/D124733

Subject: [PATCH] ld: Lookup section in output with the same name
|
|
|
|
When there are more than one input sections with the same section name,
|
|
SECNAME, linker picks the first one to define __start_SECNAME and
|
|
__stop_SECNAME symbols. When the first input section is removed by
|
|
comdat group, we need to check if there is still an output section
|
|
with section name SECNAME.
|
|
|
|
PR ld/23591
|
|
* ldlang.c (undef_start_stop): Lookup section in output with
|
|
the same name.
