Use DYLD_FRAMEWORK_PATH instead of DYLD_VERSIONED_FRAMEWORK_PATH on Safari Big Sur
https://bugs.webkit.org/show_bug.cgi?id=231058
Patch by Remy Demarest <rdemar...@apple.com> on 2021-10-01
Reviewed by David Kilzer.
Modify the DYLD environment variable that is used when compiling with staged frameworks.
We want to use DYLD_VERSIONED_FRAMEWORK_PATH to define the search path of the frameworks
for DYLD because this makes launching Safari and its child processes faster. However,
on Apple Silicon Big Sur using that environment variable does not work and results in Safari
loading frameworks from the System folder rather than from the StagedFrameworks/Safari
folder, this is because dyld on M1 does not look up that variable properly. To make sure
we actually load the frameworks from the desired location, we need to use DYLD_FRAMEWORK_PATH
instead, this makes dyld perform more stat() calls than usual to link the frameworks hence
why we prefer the other variable, but this is the only way to workaround the issue in
Big Sur on M1. In Monterey and above, this bug will be fixed in dyld so we only need this
variable before macOS 11.
Override OTHER_LDFLAGS_VERSIONED_FRAMEWORK_PATH_YES based on SDK and architecture to use
DYLD_FRAMEWORK_PATH instead of DYLD_VERSIONED_FRAMEWORK_PATH when building for macOS 11 and arm64.
