            Bug ID: 28672
           Summary: Link failure on some targets when building as PIE
           Product: binutils
           Version: 2.37
            Status: NEW
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: siddhesh at sourceware dot org
  Target Milestone: ---

When building binaries in glibc as PIE, the linker fails on multiple
architectures when handling relative relocations.  This one is for ia64:

ia64-glibc-linux-gnu-gcc -o
build-many-3/build/glibcs/ia64-linux-gnu/glibc/support/test-run-command
-nostdlib -nostartfiles -static    
build-many-3/build/glibcs/ia64-linux-gnu/glibc/csu/crt1.o
build-many-3/build/glibcs/ia64-linux-gnu/glibc/csu/crti.o
`ia64-glibc-linux-gnu-gcc  --print-file-name=crtbegin.o`
build-many-3/build/glibcs/ia64-linux-gnu/glibc/support/test-run-command.o
build-many-3/build/glibcs/ia64-linux-gnu/glibc/elf/static-stubs.o
build-many-3/build/glibcs/ia64-linux-gnu/glibc/support/libsupport_nonshared.a 
-Wl,--start-group build-many-3/build/glibcs/ia64-linux-gnu/glibc/libc.a -lgcc 
-Wl,--end-group `ia64-glibc-linux-gnu-gcc  --print-file-name=crtend.o`
build-many-3/build/glibcs/ia64-linux-gnu/glibc/csu/crtn.o
build-many-3/build/glibcs/ia64-linux-gnu/glibc/libc.a(dl-support.o): in
function `_dl_aux_init':
build-many-3/src/glibc/elf/dl-support.c:254:(.text+0x42): relocation truncated
to fit: GPREL22 against `.text'
build-many-3/build/glibcs/ia64-linux-gnu/glibc/libc.a(dl-support.o): in
function `setup_vdso':
build-many-3/src/glibc/elf/setup-vdso.h:108:(.text+0x1092): relocation

collect2: error: ld returned 1 exit status
make[3]: *** [../Rules:269:
build-many-3/build/glibcs/ia64-linux-gnu/glibc/support/test-run-command] Error
1

I'll post a more reduced reproducer soon, this is from build-many-glibcs.py; I
need the bug number as a reference to record in glibc as I enable PIE by
default there.

Affected targets:

hppa-linux-gnu
ia64-linux-gnu
csky-linux-gnuabiv2
alpha-linux-gnu
