1.10 +Subject: link_warning fix
1.11 +
1.12 +
1.13 +Hi,
1.14 +
1.15 +While cross-compiling glibc-2.2.5 for target=cris-linux using gcc-3.1 and
1.16 +binutils-2.12.90.0.7, I get an error
1.17 +
1.18 +cris-linux-gcc ../sysdeps/unix/sysv/linux/sigstack.c -c -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -g -I../include -I. -I/backup/cross-build/build-glibc-cris/signal -I.. -I../libio -I/backup/cross-build/build-glibc-cris -I../sysdeps/cris/elf -I../linuxthreads/sysdeps/unix/sysv/linux -I../linuxthreads/sysdeps/pthread -I../sysdeps/pthread -I../linuxthreads/sysdeps/unix/sysv -I../linuxthreads/sysdeps/unix -I../linuxthreads/sysdeps/cris -I../sysdeps/unix/sysv/linux/cris -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/cris -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic -nostdinc -isystem /cross/cris-linux-tools/lib/gcc-lib/cris-linux/3.1/include -isystem /cross/cris-linux/include -D_LIBC_REENTRANT -include ../include/libc-symbols.h -o /backup/cross-build/build-glibc-cris/signal/sigstack.o
1.19 +/tmp/cca7qZyI.s: Assembler messages:
1.20 +/tmp/cca7qZyI.s:87: Warning: rest of line ignored; first ignored character is `,'
1.21 +/tmp/cca7qZyI.s:87: Error: Unknown opcode: `progbits'
1.22 +make[2]: *** [/backup/cross-build/build-glibc-cris/signal/sigstack.o] Fehler 1
1.23 +
1.24 +
1.25 +The reason is that the .s file contains the following.
1.26 +
1.27 +...
1.28 + .size sigstack,.Lfe1-sigstack
1.29 +#APP
1.30 + .section .gnu.warning.sigstack
1.31 + .previous
1.32 +#NO_APP
1.33 + .section .gnu.warning.sigstack
1.34 + #,"a",@progbits
1.35 + .align 2
1.36 + .type __evoke_link_warning_sigstack,@object
1.37 +...
1.38 +
1.39 +and comments (introduced by '#') are recognized by the assembler only after
1.40 +#APP, not after #NO_APP. The workaround is to add '#APP' to the fake section
1.41 +name. The following patch works for me.

1.43 +2002-06-02 Bruno Haible <bruno@clisp.org>
1.44 +
1.45 + * include/libc-symbols.h (__as_app_line): New macro.
1.46 + (link_warning): Emit #APP line to turn comment recognition on.
