2023-11-28libsanitizer: Check assembler support for symbol assignment [PR112563]Rainer Orth1-0/+1
The recent libsanitizer import broke the build on Solaris/SPARC with the native as: /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol "__sanitizer_internal_memset" is used but not defined /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol "__sanitizer_internal_memcpy" is used but not defined /usr/ccs/bin/as: ".libs/sanitizer_errno.s", line 4247: error: symbol "__sanitizer_internal_memmove" is used but not defined Since none of the alternatives considered in the PR worked out, this patch checks if the assembler does support symbol assignment, disabling the code otherwise. This returns the code to the way it was up to LLVM 16. Bootstrapped without regressions on sparc-sun-solaris2.11 (as and gas) and i386-pc-solaris2.11 (as and gas). 2023-11-23 Rainer Orth <ro@CeBiTec.Uni-Bielefeld.DE> libsanitizer: PR sanitizer/112563 * configure.ac (libsanitizer_cv_as_sym_assign): Check for assembler symbol assignment support. * configure: Regenerate. * asan/Makefile.am (DEFS): Add @AS_SYM_ASSIGN_DEFS@. * Makefile.in, asan/Makefile.in, hwasan/Makefile.in, interception/Makefile.in, libbacktrace/Makefile.in, lsan/Makefile.in, sanitizer_common/Makefile.in, tsan/Makefile.in, ubsan/Makefile.in: Regenerate.

2023-11-15libsanitizer: merge from upstream (c425db2eb558c263)Jakub Jelinek21-179/+568
The following patch is result of libsanitizer/merge.sh from c425db2eb558c263 (yesterday evening). Bootstrapped/regtested on x86_64-linux and i686-linux (together with the follow-up 3 patches I'm about to post). BTW, seems upstream has added riscv64 support for I think lsan/tsan, so if anyone is willing to try it there, it would be a matter of copying e.g. the s390*-*-linux* libsanitizer/configure.tgt entry to riscv64-*-linux* with the obvious s/s390x/riscv64/ change in it.
2023-10-22Config,Darwin: Allow for configuring Darwin to use embedded runpath.Iain Sandoe2-2/+9
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'.

This means we have a real call and no read/write constant propagation. Unaligned memory access can be quite hot for some programs (observed on some compression algorithms with ~90% of unaligned accesses). Move them to tsan_interface_inl.h to avoid the additional call and enable constant propagation. Also reorder the actual store and memory access handling for __sanitizer_unaligned_store callbacks to enable tail calling in MemoryAccess. Depends on D107282.

On lots of CPUs it finishes in ~2 secs. But with taskset -c 0-1 it runs for hundreds of seconds effectively spinning in the barrier in the sleep loop. We now have the handy futex API in sanitizer_common. Use it instead of the passive spin loop. It makes the test run only faster with taskset -c 0-1, it runs for ~1.5 secs, while with full parallelism it still runs for ~2 secs (but consumes less CPU time). Depends on D107131.

I also tested ppc64-linux-gnu that exposed: https://reviews.llvm.org/D80864 (which is fixed on master). Abidiff looks happy and I made UBSAN and ASAN bootstrap on x86_64-linux-gnu. I'm planning to do merge from master twice a year, once now and next time short before stage1 closes. I am going to install the patches as merge from master is obvious and I haven't made anything special. libsanitizer/ChangeLog: * MERGE: Merge from master.
2020-01-24Add `--with-toolexeclibdir=' configuration optionMaciej W. Rozycki1-0/+1
Provide means, in the form of a `--with-toolexeclibdir=' configuration option, to override the default installation directory for target libraries, otherwise known as $toolexeclibdir. This is so that it is possible to get newly-built libraries, particularly the shared ones, installed in a common place, so that they can be readily used by the target system as their host libraries, possibly over NFS, without a need to manually copy them over from the currently hardcoded location they would otherwise be installed in. In the presence of the `--enable-version-specific-runtime-libs' option and for configurations building native GCC the option is ignored. config/ * toolexeclibdir.m4: New file. gcc/ * doc/install.texi (Cross-Compiler-Specific Options): Document `--with-toolexeclibdir' option. libada/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libatomic/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libffi/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * include/Makefile.in: Regenerate. * man/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libgcc/ * Makefile.in (configure_deps): Add `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. libgfortran/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libgomp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libhsail-rt/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libitm/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. libobjc/ * Makefile.in (aclocal_deps): Add `toolexeclibdir.m4'. * aclocal.m4: Include `toolexeclibdir.m4'. * configure.ac: Handle `--with-toolexeclibdir='. * configure: Regenerate. liboffloadmic/ * plugin/configure.ac: Handle `--with-toolexeclibdir='. * plugin/Makefile.in: Regenerate. * plugin/aclocal.m4: Regenerate. * plugin/configure: Regenerate. * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libphobos/ * m4/druntime.m4: Handle `--with-toolexeclibdir='. * m4/Makefile.in: Regenerate. * libdruntime/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libquadmath/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libsanitizer/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * asan/Makefile.in: Regenerate. * interception/Makefile.in: Regenerate. * libbacktrace/Makefile.in: Regenerate. * lsan/Makefile.in: Regenerate. * sanitizer_common/Makefile.in: Regenerate. * tsan/Makefile.in: Regenerate. * ubsan/Makefile.in: Regenerate. libssp/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. libstdc++-v3/ * acinclude.m4: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * doc/Makefile.in: Regenerate. * include/Makefile.in: Regenerate. * libsupc++/Makefile.in: Regenerate. * po/Makefile.in: Regenerate. * python/Makefile.in: Regenerate. * src/Makefile.in: Regenerate. * src/c++11/Makefile.in: Regenerate. * src/c++17/Makefile.in: Regenerate. * src/c++98/Makefile.in: Regenerate. * src/filesystem/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate. libvtv/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate. * testsuite/Makefile.in: Regenerate. zlib/ * configure.ac: Handle `--with-toolexeclibdir='. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * configure: Regenerate.
