commit r16-7516-gd37f4b2a1acda7c9ee93ad370ece5292ee051b7a Author: Rainer Orth <[email protected]> Date: Sat Feb 14 16:21:23 2026 +0100 Remove HAVE_AS_SPARC_GOTDATA_OP Since the introduction of gcc_cv_as_flags on SPARC, HAVE_AS_SPARC_GOTDATA_OP became undefined on sparcv9-sun-solaris2.11 with the native assembler. This happens because /bin/as is now invoked with -m64, but the test fails to assemble: /bin/as: "gotdata_op.s", line 8: error: detect global register use not covered .register pseudo-op While the test can be adjusted by the addition of .register %g2, #scratch which makes it work with both as -m32/-m64 and gas --32/--64, it turns out the whole workaround has become unnecessary: When trying all combinations of as/ld with -m32/-m64, with both the original Solaris 11.4 as/ld and the current one, as well as gas/gld 2.20.1, 2.30, and 2.46, the only cases where the test fails are when using gld 2.20.1. Solaris/SPARC requires binutils 2.30 now, and 2.20.1 can be considered ancient history on Linux/sparc64, too. Therefore the test and the code guarded by it can just go. Bootstrapped without regressions on sparc{,v9}-sun-solaris2.11 and sparc64-unknown-linux-gnu. 2026-02-12 Rainer Orth <[email protected]> gcc: * configure.ac <sparc*-*-*> (gcc_cv_as_sparc_gotdata_op): Remove. * configure: Regenerate. * config.in: Regenerate. * config/sparc/sparc.md [!HAVE_AS_SPARC_GOTDATA_OP]: Remove.
