Bug ID: 105531
Summary: [13 regression] Recent libsanitizer imports breaks
Solaris 11.3 build
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,

Target Milestone: ---
Target: i386-pc-solaris2.11, sparc-sun-solaris2.11
The recent libsanitizer import broke the build on Solaris 11.3, both SPARC and
x86:
/vol/gcc/src/hg/master/local/libsanitizer/sanitizer_common/sanitizer_linux_libcdep.cpp:
In function 'int __sanitizer::CollectStaticTlsBlocks(dl_phdr_info*,
std::size_t, void*)':
/vol/gcc/src/hg/master/local/libsanitizer/sanitizer_common/sanitizer_linux_libcdep.cpp:380:28:
error: 'struct dl_phdr_info' has no member named 'dlpi_tls_data'
380 | uptr begin = (uptr)info->dlpi_tls_data;
| ^~~~~~~~~~~~~
This happens because Solaris doesn't support dlpi_tls_data (and dlpi_tls_modid)
before Solaris 11.4 SRU 10.3.
It's not an issue for LLVM upstream which only support Solaris 11.4, but GCC
continues to support Solaris 11.3 as well.
I have an (abandoned) patch to fix this: https://reviews.llvm.org/D120059.
I'll
see if I can get it approved upstream (it needs slight modifications for
changes
to compiler-rt since it was submitted); otherwise it will have to be kept
gcc-local.
