Binutils with MCST patches
bb89747721
A couple of ld ifunc tests currently FAIL on 64-bit Solaris/x86: FAIL: ld-ifunc/ifunc-10-x86-64 FAIL: ld-ifunc/ifunc-11-x86-64 FAIL: ld-ifunc/ifunc-12-x86-64 FAIL: ld-ifunc/ifunc-13-x86-64 FAIL: ld-ifunc/ifunc-14a-x86-64 FAIL: ld-ifunc/ifunc-14b-x86-64 FAIL: ld-ifunc/ifunc-14c-x86-64 FAIL: ld-ifunc/ifunc-14d-x86-64 FAIL: ld-ifunc/ifunc-14e-x86-64 FAIL: ld-ifunc/ifunc-14f-x86-64 FAIL: ld-ifunc/ifunc-15-x86-64 FAIL: ld-ifunc/ifunc-17a-x86-64 FAIL: ld-ifunc/ifunc-17b-x86-64 FAIL: ld-ifunc/ifunc-2-local-x86-64-now FAIL: ld-ifunc/ifunc-2-local-x86-64 FAIL: ld-ifunc/ifunc-2-x86-64-now FAIL: ld-ifunc/ifunc-2-x86-64 FAIL: ld-ifunc/ifunc-20-x86-64 FAIL: ld-ifunc/pr17154-x86-64-now FAIL: ld-ifunc/pr17154-x86-64 For one, the actual error is weird: ./ld-new: target elf64-x86-64 not found failed with: <./ld-new: target elf64-x86-64 not found>, no expected output FAIL: ld-ifunc/ifunc-10-x86-64 although ld -V does report the elf_x86_64 emulation as supported: $ ./ld/ld-new -V GNU ld (GNU Binutils) 2.34.50.20200328 Supported emulations: elf_x86_64_sol2 elf_x86_64 [...] When using ld -m elf_x86_64_sol2 instead, one of the testcases links successfully. However, there's no point in pursuing this: Solaris does not support ifunc, as can be seen in <sys/elf.h>: /* * GNU/Linux specific symbol type not used by Solaris */ #define STT_GNU_IFUNC 10 and never will, given that it has symbol capabilities as solution to effectively the same problem: http://www.linker-aliens.org/blogs/rie/entry/symbol_capabilitie/ Therefore this patch disables ifunc testing on Solaris completely by removing Solaris from binutils/testsuite/lib/binutils-common.exp (supports_gnu_osabi). The ifunc part is justified above. SHF_GNU_MBIND is in the OS-specific range and conflicts with #define SHF_SUNW_REALLOC 0x01000000 /* internal: krtld realloc */ While the comment suggests this might be relocatable without too much problems, the description of mbind (no formal spec AFAICS, just the comment in the binutils patch submission) strongly suggests that this isn't relevant to Solaris at all. Indirectly, clearing supports_gnu_osabi on Solaris disables supports_gnu_unique. Again, Solaris <sys/elf.h> has /* * GNU/Linux specific binding not used by Solaris */ #define STB_GNU_UNIQUE 10 so this seems the right thing to do. Afterwards, one can remove the explicit mentions of *-*-solaris2* in quite a number of (but not all) the ld-ifunc dump file notarget lists. There's one fallout, though: two gas tests now XPASS because they are xfail'ed for !supports_gnu_osabi: XPASS: mbind sections 12 XPASS: mbind section contents 16 XPASS: mbind sections 16 XPASS: mbind section contents 16 To fix that, I've changed #xfail: ![supports_gnu_osabi] to notarget. Tested on x86_64-pc-solaris2.11, i386-pc-solaris2.11, x86_64-pc-linux-gnu, and i686-pc-linux-gnu. ld: * testsuite/ld-ifunc/ifunc-10-i386.d: Remove *-*-solaris2* from notarget. * ifunc-11-i386.d: Likewise. * ifunc-12-i386.d: Likewise. * ifunc-13-i386.d: Likewise. * ifunc-14a-i386.d: Likewise. * ifunc-14b-i386.d: Likewise. * ifunc-14c-i386.d: Likewise. * ifunc-14d-i386.d: Likewise. * ifunc-14e-i386.d: Likewise. * ifunc-14f-i386.d: Likewise. * ifunc-15-i386.d: Likewise. * ifunc-16-i386-now.d: Likewise. * ifunc-16-i386.d: Likewise. * ifunc-17a-i386.d: Likewise. * ifunc-17b-i386.d: Likewise. * ifunc-18a-i386.d: Likewise. * ifunc-18b-i386.d: Likewise. * ifunc-19a-i386.d: Likewise. * ifunc-19b-i386.d: Likewise. * ifunc-2-i386-now.d: Likewise. * ifunc-2-i386.d: Likewise. * ifunc-2-local-i386-now.d: Likewise. * ifunc-2-local-i386.d: Likewise. * ifunc-20-i386.d: Likewise. * ifunc-21-i386.d: Likewise. * ifunc-22-i386.d: Likewise. * ifunc-5a-i386.d: Likewise. * ifunc-5a-local-i386.d: Likewise. * ifunc-5b-i386.d: Likewise. * ifunc-5b-local-i386.d: Likewise. * ifunc-5r-local-i386.d: Likewise. * ifunc-6a-i386.d: Likewise. * ifunc-6b-i386.d: Likewise. * ifunc-7a-i386.d: Likewise. * ifunc-7b-i386.d: Likewise. * ifunc-8-i386.d: Likewise. * ifunc-9-i386.d: Likewise. * pr17154-i386-now.d: Likewise. * pr17154-i386.d: Likewise. * ifunc-23a-x86.d: Remove notarget. * ifunc-24a-x86.d: Likewise. * ifunc-25a-x86.d: Likewise. gas: * testsuite/gas/elf/section12a.d: Use notarget instead of xfail. * testsuite/gas/elf/section12b.d: Likewise. * testsuite/gas/elf/section16a.d: Likewise. * testsuite/gas/elf/section16b.d: Likewise. binutils: * testsuite/lib/binutils-common.exp (supports_gnu_osabi): Don't enable on *-*-solaris*. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
