* i386: Fix build with --enable-fortify=3Adhemerval Zanella Netto2023-07-261-21/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i386 string routines provide multiple internal definitions for memcpy, memmove, and mempcpy chk routines: $ objdump -t libc.a | grep __memcpy_chk 00000000 g F .text 0000000e __memcpy_chk 00000000 g F .text 00000013 __memcpy_chk $ objdump -t libc.a | grep __mempcpy_chk 00000000 g F .text 0000000e __mempcpy_chk 00000000 g F .text 00000013 __mempcpy_chk $ objdump -t libc.a | grep __memmove_chk 00000000 g F .text 0000000e __memmove_chk 00000000 g F .text 00000013 __memmove_chk Although is not an issue for normal static builds, with fortify=3 glibc itself might use the fortify chk functions and thus static build might fail with multiple definitions. For instance: x86_64-glibc-linux-gnu-gcc -m32 -march=i686 -o [...]math/test-signgam-uchar-static -nostdlib -nostartfiles -static -static-pie [...] x86_64-glibc-linux-gnu/bin/ld: [...]/libc.a(mempcpy-ia32.o): in function `__mempcpy_chk': [...]/glibc-git/string/../sysdeps/i386/i686/mempcpy.S:32: multiple definition of `__mempcpy_chk'; [...]/libc.a(mempcpy_chk-nonshared.o):[...]/debug/../sysdeps/i386/mempcpy_chk.S:28: first defined here collect2: error: ld returned 1 exit status make[2]: *** [../Rules:298: There is no need for mem*-nonshared.S, the __mem*_chk routines are already provided by the assembly routines. Checked on i686-linux-gnu with gcc 13 built with fortify=1,2,3 and without fortify. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines
