Bug ID: 20427
Summary: Solaris rtld on SPARC does not allow R_SPARC_UA64 or
R_SPARC_64 relocations in 32-bit executables
Product: binutils
Version: 2.25
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: stefan.teleman at oracle dot com
Target Milestone: ---
Host: sparc-sun-solaris2.12

test case demonstrating the bug
This bug is present in Binutils 2.25.1 and 2.26.1.
This bug can be verified on Solaris 11 as well as Solaris 12.
With a hand-written SPARC assembler translation unit, containing
the following:
.data
.align 8
.global .gomp_critical_user_
.comm .gomp_critical_user_, 64, 8
The resulting 32-bit SPARC *.o ELF -- asembled with gas - is then
linked into a shared library.
When linking this shared library in a 32-bit SPARC program, trying to
run the test program results in:
ld.so.1: main32: fatal: relocation error: file
/builds/steleman/userland-s12-binutils-gas-24380705/components/binutils/build/sparcv9/gas/libtest32.so:
symbol .gomp_critical_user_: invalid relocation type for ELFCLASS32: 54
./testit-gcc.sh: line 29: 441437 Killed ./main32
The link-editing itself succeeds without warnings.
The attachment gnu-as-bad-reloc-test.tar.bz2 demonstrates the bug.
The proposed patch (attached) cures this bug. The 32-bit test program
now succeeds, and works as expected.
