Bug #: 15365
Summary: MIPS linker hits assertion with -mabi=64 accessing
__ehdr_start
Product: binutils
Version: 2.24 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: ld
AssignedTo: unassig...@sourceware.org
ReportedBy: s...@gcc.gnu.org
Classification: Unclassified
A recent change to glibc caused my ToT MIPS builds to fail. The test case
included below demonstrates the linker assertion I am hitting when building
glibc.
% cat ehdr.c
#include <stdio.h>
#include <elf.h> /* has definition of Elf32_Ehdr & Elf64_Ehdr */
extern const Elf32_Ehdr __ehdr_start __attribute__ ((weak));
main()
{
void *x;
x = (void *) &__ehdr_start;
printf("0x%x\n", x);
}
% mips-mti-linux-gnu-gcc -mips64r2 -mabi=64 ehdr.c -o x
/local/home/sellcey/nightly2/install-mips-mti-linux-gnu/lib/gcc/mips-mti-linux-gnu/4.9.0/../../../../mips-mti-linux-gnu/bin/ld:
BFD (GNU Binutils) 2.23.52.20130411 assertion fail
/local/home/sellcey/nightly2/src/binutils/bfd/elfxx-mips.c:3457
collect2: error: ld returned 1 exit status
The assertion in elfxx-mips.c is:
/* This function shouldn't be called for symbols that live in the global
area of the GOT. */
BFD_ASSERT (h == NULL || h->global_got_area == GGA_NONE);
