2025-04-10libbacktrace: Add hpux fileline supportJohn David Anglin1-1/+35
Fixes libstdc++ stacktrace tests. 2025-04-10 John David Anglin <danglin@gcc.gnu.org> libbacktrace/ChangeLog: * fileline.c (hpux_get_executable_path): New. (fileline_initialize): Add pass to get hpux executable path.

2025-04-09bootstrap/119680 - fix cross-compiler build with --enable-host-sharedRichard Biener2-5/+18
It seems that at least when cross-compiling at least collect2 pulls in objects from libbacktrace.a which is linked via LIBDEPS. But libbacktrace for the host is only built -fPIC with --enable-host-shared but not -fPIE with --enable-host-pie so this fails. The following teaches libbacktrace about --enable-host-pie and handles it similar to libcpp. PR bootstrap/119680 libbacktrace/ * configure.ac (--enable-host-pie): Handle by setting PIC_FLAG to -fPIE. * configure: Regenerate.

2025-01-28arm: libbacktrace: Check if the compiler supports __sync atomicsRichard Earnshaw2-0/+33
Older versions of the Arm architecture lack support for __sync operations directly in hardware and require calls into appropriate operating-system hooks. But such hooks obviously don't exist in a freestanding environment. Consquently, it is incorrect to assume during configure that such functions will exist and we need a configure-time check to determine whether or not these routines will work. libbacktrace: * configure.ac: Always check if the compiler supports __sync operations. * configure: Regenerated.

2024-07-11libbacktrace: avoid infinite recursionIan Lance Taylor3-42/+134
We could get an infinite recursion in an odd case in which a .gnu_debugdata section was added to a debug file, and mini_debuginfo was put into the debug file, and the debug file was put into a /usr/lib/debug directory to be found by build ID.
