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.

2023-10-22Config,Darwin: Allow for configuring Darwin to use embedded runpath.Iain Sandoe2-5/+73
Recent Darwin versions place contraints on the use of run paths specified in environment variables. This breaks some assumptions in the GCC build. This change allows the user to configure a Darwin build to use '@rpath/libraryname.dylib' in library names and then to add an embedded runpath to executables (and libraries with dependents). The embedded runpath is added by default unless the user adds '-nodefaultrpaths' to the link line. For an installed compiler, it means that any executable built with that compiler will reference the runtimes installed with the compiler (equivalent to hard-coding the library path into the name of the library). During build-time configurations any "-B" entries will be added to the runpath thus the newly-built libraries will be found by exes. Since the install name is set in libtool, that decision needs to be available here (but might also cause dependent ones in Makefiles, so we need to export a conditional). This facility is not available for Darwin 8 or earlier, however the existing environment variable runpath does work there. We default this on for systems where the external DYLD_LIBRARY_PATH does not work and off for Darwin 8 or earlier. For systems that can use either method, if the value is unset, we use the default (which is currently DYLD_LIBRARY_PATH). ChangeLog: * configure: Regenerate. * configure.ac: Do not add default runpaths to GCC exes when we are building -static-libstdc++/-static-libgcc (the default). * libtool.m4: Add 'enable-darwin-at-runpath'.
