arm: properly range check immediate operands of VSHL and VQSHL These two, other than VQSHLU, didn't have their immediates properly range checked so far. (Re-sending unchanged from the original v2 due to never having got an answer to https://sourceware.org/ml/binutils/2013-04/msg00121.html.) gas/ 2015-01-12 Jan Beulich <jbeulich@suse.com> * gas/config/tc-arm.c (do_neon_shl_imm): Check immediate range. (do_neon_qshl_imm): Likewise. gas/testsuite/ 2015-01-12 Jan Beulich <jbeulich@suse.com> * gas/arm/neon-addressing-bad.s: Add test for invalid VSHL, VQSHL, and VQSHLU immediates. * gas/arm/neon-addressing-bad.l: Update accordingly.

* gas/arm/neon-addressing-bad.s: Add test for invalid VSHL,
VQSHL, and VQSHLU immediates.
* gas/arm/neon-addressing-bad.l: Update accordingly.
gas/avr: Prevent incorrect overflow errors for diff fixups. When fixups are converted to a difference type within md_apply_fix, we previously left the contents of VALP (the value that was initially computed within write.c:fixup_segment) unchanged. This is harmless, except that this value is used within write.c:fixup_segment once we return from md_apply_fix to perform an overflow check. In some cases, the value computed in write.c:fixup_segment is so wrong that an overflow error can be triggered. These errors are incorrect. This patch avoids the overflow errors by adjusting the value in write.c:fixup_segment using the VALP pointer in md_apply_fix. A test for this issue is included. gas/ChangeLog: * config/tc-avr.c (md_apply_fix): Update the contents of VALP for diff fixups. gas/testsuite/ChangeLog: * gas/avr/large-debug-line-table.d: New file. * gas/avr/large-debug-line-table.s: New file.

AVR: Assembler now prepares for linker relaxation by default. Have the assembler prepare for linker relaxation by default. This means that users will be able to make use of linker relaxation without having to adjust the assembler flags, this can make life easier when compiling libraries. Having this on by default in the assembler should make no difference to the assembler code produced, however, some of the debug information will be slightly less compressed. A few tests needed to be updated as a result of this change as they relied on linker relaxation support being off by default. I've tightened up the definition of which sections can be relaxed on AVR as part of this commit, the assembler used to think that all non-debugging sections could be relaxed, when in reality only code sections can be relaxed for AVR. The previous definition was not dangerous, just over cautious. The new tighter definition allows an extra test (gas/testsuite/gas/all/forward.d) to continue to pass. gas/ChangeLog: * config/tc-avr.c (struct avr_opt_s): Change link_relax to no_link_relax, extend comment. (enum options): Add new OPTION_NO_LINK_RELAX. (md_longopts): Add entry for -mno-link-relax. (md_parse_option): Handle OPTION_NO_LINK_RELAX, and update OPTION_LINK_RELAX. (md_begin): Initialise linkrelax from no_link_relax. (md_show_usage): Include -mno-link-relax option. (relaxable_section): Only allocatable code sections can be relaxed. * config/tc-avr.h (TC_LINKRELAX_FIXUP): Define. gas/testsuite/ChangeLog: * gas/all/gas.exp: Test will not pass on AVR due to linker relaxation support. * gas/avr/noreloc_withoutrelax.d: Add -mno-link-relax option. * gas/avr/link-relax-elf-flag-clear.d: Likewise. ld/testsuite/ChangeLog: * ld/testsuite/ld-avr/relax-elf-flags-02.d: Add -mno-link-relax option. * ld/testsuite/ld-avr/relax-elf-flags-03.d: Likewise. * ld/testsuite/ld-avr/relax-elf-flags-04.d: Likewise. * ld/testsuite/ld-avr/relax-elf-flags-05.d: Likewise. * ld/testsuite/ld-avr/relax-elf-flags-06.d: Likewise.
