It depends:
as/ld gas/ld gas/gld
Solaris 8 no no yes
Solaris 9 no no yes
Solaris 10 yes no yes
Solaris 11 yes yes yes
On Solaris 8 and 9, as fails to assemble the testcase, with gas, ld
SEGVs when linking.
On Solaris 10, as assembles the test just fine, but ld cannot deal with
gas 2.21 output:
ld: fatal: relocation error: R_SPARC_GOTDATA_HIX22: file gotdata.o: symbol
<unknown>: offset 0xff370163 is non-aligned
ld: fatal: relocation error: R_SPARC_GOTDATA_LOX10: file gotdata.o: symbol
<unknown>: offset 0xff370167 is non-aligned
ld: fatal: file gotdata: creation interrupted: Error 0
On Solaris 11, all is fine.
I get the same results with an unmodifed tree and the following
simplified version of my patch.
Ok for mainline?
