--- Comment #21 from cvs-commit at gcc dot gnu.org <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Nick Alcock <n...@sourceware.org>: https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=e755667f94f2579056fb5210eed525dafebb96f3 commit e755667f94f2579056fb5210eed525dafebb96f3 Author: Nick Alcock <nick.alc...@oracle.com> Date: Fri Dec 13 15:19:17 2019 +0000 libctf, elfcpp, gold: do not assume that <byteswap.h> contains bswap_* At least one C library (uclibc-ng) defines some of these only when the compiler is GCC. We might as well test for all three cases and handle any of them being missing. Very similar code exists in libctf and split between elfcpp and gold: fix both. (Also sync up elfcpp with a change made to libctf swap.h a few months ago: since there is no out-of-line definition of the bswap replacements, they should be declared static inline, not just inline, to prevent the linker generating out-of-line references to them.) PR libctf/25120 libctf/ * configure.ac: Check for bswap_16, bswap_32, and bswap_64 decls. * swap.h (bswap_16): Do not assume that presence of <byteswap.h> means this is declared. (bswap_32): Likewise. (bswap_64): Likewise. (bswap_identity_64): Remove, unused. * configure: Regenerated. * config.h.in: Likewise. gold/ * configure.ac: Check for bswap_16, bswap_32, and bswap_64 decls. * configure: Regenerated. * config.h.in: Likewise. elfcpp/ * elfcpp_swap.h (bswap_16): Do not assume that presence of <byteswap.h> means this is declared. Make static inline, matching recent change to libctf, since there is no non-inline definition of these functions. (bswap_32): Likewise. (bswap_64): Likewise. -- You are receiving this mail because: You are on the CC list for the bug.
