2015-07-16[AArch64] Mark single precision pseudo registers unavailable if invalidPierre Langlois2-1/+10
I noticed two failure in gdb.trace/mi-trace-frame-collected.exp: FAIL: gdb.trace/mi-trace-frame-collected.exp: live: -trace-frame-collected (register) FAIL: gdb.trace/mi-trace-frame-collected.exp: tfile: -trace-frame-collected (register) In these cases, we are not collecting registers so the MI command -trace-frame-collected should only give us the value of the PC. However, it also gives us all of the single precision pseudo registers, initialized with 0x0. We can reproduce this error by simply issuing the 'maint print cooked-register' when no inferior is connected: ~~~ ... (gdb) maint print cooked-register Name Nr Rel Offset Size Type Cooked value x0 0 0 0 8 long <unavailable> x1 1 1 8 8 long <unavailable> ... d30 130 62 1540 8 *1 <unavailable> d31 131 63 1548 8 *1 <unavailable> s0 132 64 1556 4 *1 0x00000000 s1 133 65 1560 4 *1 0x00000000 s2 134 66 1564 4 *1 0x00000000 ... s28 160 92 1668 4 *1 0x00000000 s29 161 93 1672 4 *1 0x00000000 s30 162 94 1676 4 *1 0x00000000 s31 163 95 1680 4 *1 0x00000000 h0 164 96 1684 2 *1 <unavailable> h1 165 97 1686 2 *1 <unavailable> h2 166 98 1688 2 *1 <unavailable> ... ~~~ It turns out GDB does not check if S registers are valid before returning a value for them. It should return <unavailable> in this case. gdb/ChangeLog: * aarch64-tdep.c (aarch64_pseudo_read_value): Mark S register as unavailable if invalid.

Fix the ARI warning about the use of unsigned long long. We can't use ULONGEST as this is defined unsigned long on 64-bit systems. This will result in a compile error when storing a pointer to an unsigned long long structure field (declared in perf_event.h as __u64) in a ULONGEST * variable.

2015-07-14Remove CHECK_TYPEDEF, use check_typedef insteadSimon Marchi51-131/+179
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit annoying. It makes unclear the fact that the "type" variables gets overwritten. It has actually bitten me a few times. I think the following, explicit form, is better. type = check_typedef (type); This patches changes all instances of CHECK_TYPEDEF for an equivalent call to check_typedef. The bulk of the change was done with this sed: sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c The ChangeLog was generated using David Malcom's generate_changelog.py. I manually fixed those places where it gets the wrong function name, hopefully all of them.

2015-07-14Make default compression gABI compliantH.J. Lu18-41/+93
All programs in binutils+gdb git repo now support gABI compression with the SHF_COMPRESSED bit. This patch makes the zlib-gabi option as compression default for gas, gold, ld and objcopy, instead of the zlib-gnu option whose outputs are incompatible with gABI. binutils/ * objcopy.c (copy_file): Set BFD_COMPRESS_GABI if not zlib-gnu. * doc/binutils.texi: Change --compress-debug-sections and --compress-debug-sections=zlib to zlib-gabi. binutils/testsuite/ * binutils-all/compress.exp: Update. gas/ * as.c (parse_args): Make --compress-debug-sections and --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * doc/as.texinfo: Change --compress-debug-sections and --compress-debug-sections=zlib to zlib-gabi. gold/ * compressed_output.cc (Output_compressed_section::set_final_data_size): Make --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * testsuite/Makefile.am (flagstest_compress_debug_sections.check): Expect ".debug_.*" with the SHF_COMPRESSED bit, instead of ".zdebug_". * testsuite/Makefile.in: Regenerated. ld/ * emultempl/elf32.em (gld${EMULATION_NAME}_handle_option): Make --compress-debug-sections=zlib the same as --compress-debug-sections=zlib-gabi. * ld.texinfo: Change --compress-debug-sections=zlib to zlib-gabi. ld/testsuite/ * ld-elf/zlibbegin.rS: Updated to .debug_.* with the SHF_COMPRESSED bit. * ld-elf/zlibnormal.rS: Likewise.
