* Step.init() now takes an options struct
* Step.init() now captures a small stack trace and stores it in the
Step so that it can be accessed when printing user-friendly debugging
information, including the lines of code that created the step in
question.
Changes only pertain arm64 as for x86_64 turns out we are
missing one additional feature which is synthesising unwind info
from only eh frame records, or at least this is what it looks like
when I analysed the output of Apple's ld.
When outputting the names section, we should output the actual symbol
name rather than the import name. This makes sure that symbols with
an explicit name set have the correct name but retain the import name
too.
We also now correctly mangle the name of an extern function with an
explicit library name. This ensures that functions that have a
different library name, but the same import/function name, can be
resolved correctly with other modules and don't resolve to the
same symbol.
Adds a linker test case for each possible export case. This means
one where no exports are done (i.e. no flags set), when the -dynamic
flag is set, and finally when --export=<value> flag(s) are set.
Adds a test for inferring features based on a different object file.
Also provides a test case where cpu features are explicitly set on
a library where the end result will output said target features.
* Sema: implement linksection on functions
* Implement function linksection in Sema.
* Don't clobber function linksection/align/addrspace in Sema.
* Fix copy-paste typo in tests.
* Add a bunch of missing test_step.dependOn.
* Fix checkInSymtab match.
Closes#12546
When testing the Wasm linker for the producers section
we do not ever want to strip the binary as this will remove
the producers section in release-small.
This fixes the CI errors by d086b371f0e21e5029e1b0d05838b87502eb63e6
This also turns off non-debug modes for the bss linker tests for
Wasm. This is done as it's not required to guarantee to zero out
the bss section for non-debug modes.
2c3d87b168bf522f538e78325fdae71c320e6e20 introduced a new test that
passes on macOS but fails on other operating systems. This commit makes
it only run on macOS.
Move common tests by target file format (Wasm, MachO) into helper
functions in `link.zig`, and sort alphabetically within for easier
tracking versus file organization on disk.
