In-Reply-To: <20211213030233.2286715-1-siddhesh@sourceware.org> (Siddhesh Poyarekar via Libc-alpha's message of "Mon, 13 Dec 2021 08:32:33 +0530")
We recently started building libc.a with -DPIC on arm:
gcc ../sysdeps/unix/sysv/linux/arm/setcontext.S -c -I../include -I/builddir/build/BUILD/glibc-2.34.9000-376-g4435c29892/build-armv7hl-redhat-linuxeabi/stdlib -I/builddir/build/BUILD/glibc-2.34.9000-376-g4435c29892/build-armv7hl-redhat-linuxeabi -I../sysdeps/unix/sysv/linux/arm/le -I../sysdeps/unix/sysv/linux/arm -I../sysdeps/arm/nptl -I../sysdeps/unix/sysv/linux/include -I../sysdeps/unix/sysv/linux -I../sysdeps/nptl -I../sysdeps/pthread -I../sysdeps/gnu -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix/arm -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/arm/le/armv7/multiarch -I../sysdeps/arm/armv7/multiarch -I../sysdeps/arm/le/armv7 -I../sysdeps/arm/armv7 -I../sysdeps/arm/armv6t2 -I../sysdeps/arm/armv6 -I../sysdeps/arm/le -I../sysdeps/arm/include -I../sysdeps/arm -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754 -I../sysdeps/generic -I.. -I../libio -I. -nostdinc -isystem /usr/lib/gcc/armv7hl-redhat-linux-gnueabi/11/include -isystem /usr/include -D_LIBC_REENTRANT -include /builddir/build/BUILD/glibc-2.34.9000-376-g4435c29892/build-armv7hl-redhat-linuxeabi/libc-modules.h -DMODULE_NAME=libc -include ../include/libc-symbols.h -DPIC -DTOP_NAMESPACE=glibc -DASSEMBLER -g -Wa,--generate-missing-build-notes=yes -Werror=undef -Wa,--noexecstack -o /builddir/build/BUILD/glibc-2.34.9000-376-g4435c29892/build-armv7hl-redhat-linuxeabi/stdlib/setcontext.o -MD -MP -MF /builddir/build/BUILD/glibc-2.34.9000-376-g4435c29892/build-armv7hl-redhat-linuxeabi/stdlib/setcontext.o.dt -MT /builddir/build/BUILD/glibc-2.34.9000-376-g4435c29892/build-armv7hl-redhat-linuxeabi/stdlib/setcontext.o
Before, we had this (no -DPIC between “../include/libc-symbols.h” and
“-DTOP_NAMESPACE=glibc“):
gcc ../sysdeps/unix/sysv/linux/arm/setcontext.S -c -I../include -I/builddir/build/BUILD/glibc-2.34.9000-326-g4df1fa6ddc/build-armv7hl-redhat-linuxeabi/stdlib -I/builddir/build/BUILD/glibc-2.34.9000-326-g4df1fa6ddc/build-armv7hl-redhat-linuxeabi -I../sysdeps/unix/sysv/linux/arm/le -I../sysdeps/unix/sysv/linux/arm -I../sysdeps/arm/nptl -I../sysdeps/unix/sysv/linux/include -I../sysdeps/unix/sysv/linux -I../sysdeps/nptl -I../sysdeps/pthread -I../sysdeps/gnu -I../sysdeps/unix/inet -I../sysdeps/unix/sysv -I../sysdeps/unix/arm -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/arm/le/armv7/multiarch -I../sysdeps/arm/armv7/multiarch -I../sysdeps/arm/le/armv7 -I../sysdeps/arm/armv7 -I../sysdeps/arm/armv6t2 -I../sysdeps/arm/armv6 -I../sysdeps/arm/le -I../sysdeps/arm/include -I../sysdeps/arm -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754 -I../sysdeps/generic -I.. -I../libio -I. -nostdinc -isystem /usr/lib/gcc/armv7hl-redhat-linux-gnueabi/11/include -isystem /usr/include -D_LIBC_REENTRANT -include /builddir/build/BUILD/glibc-2.34.9000-326-g4df1fa6ddc/build-armv7hl-redhat-linuxeabi/libc-modules.h -DMODULE_NAME=libc -include ../include/libc-symbols.h -DTOP_NAMESPACE=glibc -DASSEMBLER -g -Wa,--generate-missing-build-notes=yes -Werror=undef -Wa,--noexecstack -o /builddir/build/BUILD/glibc-2.34.9000-326-g4df1fa6ddc/build-armv7hl-redhat-linuxeabi/stdlib/setcontext.o -MD -MP -MF /builddir/build/BUILD/glibc-2.34.9000-326-g4df1fa6ddc/build-armv7hl-redhat-linuxeabi/stdlib/setcontext.o.dt -MT /builddir/build/BUILD/glibc-2.34.9000-326-g4df1fa6ddc/build-armv7hl-redhat-linuxeabi/stdlib/setcontext.o
I'm going to send a patch, but I can't really test it.
Thanks,
Florian
