This is a residual of the $FreeBSD$ removal.

libc/tests: Further refine the condition for installing h_raw

2024-06-09T14:08:31+00:00

See 8164d511d6a6 ("libc/tests: Fix installation without MK_TOOLCHAIN")
for some background.  Here we should really be testing MK_CLANG instead,
since that's what gates compilation of libclang_rt.

libc/tests: Fix installation without MK_TOOLCHAIN

2024-05-28T12:24:43+00:00

There is some exotic conditional logic here to avoid building a
particular test if a certain UBSAN library isn't present in the
toolchain sysroot.  This causes build failures for me when doing an
"installworld WITHOUT_TOOLCHAIN=", which I do frequently during tests.

I believe the problem is that SYSROOT is unset during installworld, so
the build sees the host's copy of libclang_rt.ubsan_standalone.a and
then tries to install a binary that wasn't built during buildworld.  Try
to make the check a bit less fragile.

lib{c,sys}: move auxargs more firmly into libsys

2024-02-19T22:44:08+00:00

Continue to filter the public interface (elf_aux_info()), but entierly
relocate the private interfaces (_elf_aux_info(),
__init_elf_aux_vector(), and __elf_aux_vector) to libsys.

This ensures that rtld updates the correct (only) copy of
__elf_aux_vector.  After 968a18975adc9c2a619bb52aa2f009de99fc9e24
updates were confused and __getosreldate was failing, causing
the system to fall back to compat compat12 syscalls in some cases.

Return to explicitly linking libc to libsys and link libthr with libc
and libsys (in that order).

Allow using sanitizers for ssp tests with out-of-tree compiler

2021-03-12T17:15:33+00:00

With an out-of-tree Clang, we can use the -resource-dir flag when linking
to point it at the runtime libraries from the current SYSROOT.
This moves the path to the clang-internal library directory to a separate
.mk file that can be used by Makefiles that want to find the sanitizer
libraries. I intend to re-use this .mk file for my upcoming changes that
allow building the entire base system with ASAN/UBSAN/MSAN.

Rename NO_WERROR -> MK_WERROR=no

2021-01-07T09:31:03+00:00

As suggested in D27598. This also supports MK_WERROR.clang=no and
MK_WERROR.gcc=no to support the existing NO_WERROR. uses.

Disable ssp raw test without ASAN

2020-10-28T23:10:54+00:00

r366981 disabled ASAN when it might not be reliable (with an external
compiler), but this test is broken without ASAN so disable it completely
in that case.

Only use ASAN when using the in-tree compiler

2020-10-23T22:27:45+00:00

When building FreeBSD 11 on a FreeBSD 12 system with
CROSS_TOOLCHAIN=llvm10 we end up trying to link against the packaged
version of the sanitizer library.  This resulted in a requirement for
getentropy(3) which is not present in FreeBSD 11.
