2023-08-07libtool.m4: fix nm BSD flag detectionNick Alcock1-44/+45
Libtool needs to get BSD-format (or MS-format) output out of the system nm, so that it can scan generated object files for symbol names for -export-symbols-regex support. Some nms need specific flags to turn on BSD-formatted output, so libtool checks for this in its AC_PATH_NM. Unfortunately the code to do this has a pair of interlocking flaws: - it runs the test by doing an nm of /dev/null. Some platforms reasonably refuse to do an nm on a device file, but before now this has only been worked around by assuming that the error message has a specific textual form emitted by Tru64 nm, and that getting this error means this is Tru64 nm and that nm -B would work to produce BSD-format output, even though the test never actually got anything but an error message out of nm -B. This is fixable by nm'ing *nm itself* (since we necessarily have a path to it). - the test is entirely skipped if NM is set in the environment, on the grounds that the user has overridden the test: but the user cannot reasonably be expected to know that libtool wants not only nm but also flags forcing BSD-format output. Worse yet, one such "user" is the top-level Cygnus configure script, which neither tests for nor specifies any BSD-format flags. So platforms needing BSD-format flags always fail to set them when run in a Cygnus tree, breaking -export-symbols-regex on such platforms. Libtool also needs to augment $LD on some platforms, but this is done unconditionally, augmenting whatever the user specified: the nm check should do the same. One wrinkle: if the user has overridden $NM, a path might have been provided: so we use the user-specified path if there was one, and otherwise do the path search as usual. (If the nm specified doesn't work, this might lead to a few extra pointless path searches -- but the test is going to fail anyway, so that's not a problem.) (Tested with NM unset, and set to nm, /usr/bin/nm, my-nm where my-nm is a symlink to /usr/bin/nm on the PATH, and /not-on-the-path/my-nm where *that* is a symlink to /usr/bin/nm.) ChangeLog: * libtool.m4 (LT_PATH_NM): Try BSDization flags with a user-provided NM, if there is one. Run nm on itself, not on /dev/null, to avoid errors from nms that refuse to work on non-regular files. Remove other workarounds for this problem. Strip out blank lines from the nm output. fixincludes/ChangeLog: * configure: Regenerate. gcc/ChangeLog: * configure: Regenerate. libatomic/ChangeLog: * configure: Regenerate. libbacktrace/ChangeLog: * configure: Regenerate. libcc1/ChangeLog: * configure: Regenerate. libffi/ChangeLog: * configure: Regenerate. libgfortran/ChangeLog: * configure: Regenerate. libgm2/ChangeLog: * configure: Regenerate. libgomp/ChangeLog: * configure: Regenerate. libitm/ChangeLog: * configure: Regenerate. libobjc/ChangeLog: * configure: Regenerate. libphobos/ChangeLog: * configure: Regenerate. libquadmath/ChangeLog: * configure: Regenerate. libsanitizer/ChangeLog: * configure: Regenerate. libssp/ChangeLog: * configure: Regenerate. libstdc++-v3/ChangeLog: * configure: Regenerate. libvtv/ChangeLog: * configure: Regenerate. lto-plugin/ChangeLog: * configure: Regenerate. zlib/ChangeLog: * configure: Regenerate.

2022-10-11Generic configury support for shared libs on VxWorksOlivier Hainque1-0/+24
This change adds the configury bits to activate the build of shared libs on VxWorks ports configured with --enable-shared, for libraries variants where this is generally supported (rtp, code model !large - currently not compatible with -fPIC). Set lt_cv_deplibs_check_method in libtool.m4, so the build of libraries know how to establish dependencies. This is useful in configurations such as aarch64 where proper support of LSE relies on accurate dependency information between libstdc++ and libgcc_s to begin with. Regenerate configure scripts to reflect libtool.m4 change. 2022-10-09 Olivier Hainque <hainque@adacore.com> * libtool.m4 (*vxworks*): When enable_shared, set dynamic_linker and friends for rtp !large.

2022-04-05libbacktrace: don't skip initial aligned byte in uncompressed blockIan Lance Taylor1-1/+1
Patch from Rui Ueyama, who says: libbacktrace occasionally fails to decompress compressed debug info even though the sections contain valid zlib streams. The cause of the issue is an off-by-one error. If a zlib data block is a plain data (uncompressed data), the next two bytes contain the size of the block. These two bytes value is byte- aligned, so if we read-ahead more than 8 bits, we need to unread it. So, the correct condition to determine whether or not we need to unread a byte is bits >= 8 and not bits > 8. Due to this error, if the last read bits happened to end at a byte boundary, the next byte would be skipped. That caused the decompression failure. This bug was originally reported against the mold linker. rui314/mold#402 * elf.c (elf_zlib_inflate): Don't skip initial aligned byte in uncompressed block.
