2019-02-21PowerPC __tls_get_addr arg parsingAlan Modra1-40/+52
The syntax we ended up with for -m32 -fPIC calls to __tls_get_addr is rather weird. bl __tls_get_addr+0x8000(gd0@tlsgd)@plt This came about by accident, probably due to requiring the arg reloc before the call reloc. Of course the @plt really belongs with __tls_get_addr since it affects the call rather than the call arg, and it isn't a great deal of trouble to ensure the relocs are emitted in the correct order. This patch supports a newer syntax, like so: bl __tls_get_addr+0x8000@plt(gd0@tlsgd) gas/ * config/tc-ppc.c (parse_tls_arg): New function, extracted.. (md_assembler): ..from here. Call it after parsing other suffix modifiers too. ld/ * testsuite/ld-powerpc/tls32.s: Test new @plt syntax.

2019-02-10gas: Pass max_bytes to TC_FRAG_INITH.J. Lu17-22/+52

Lu <hjl.tools@gmail.com> Date: Wed Mar 7 04:18:45 2018 -0800 x86: Rewrite NOP generation for fill and alignment increased MAX_MEM_FOR_RS_ALIGN_CODE to 4095 which resulted in increase of assembler time and memory usage by 5 times for inputs with many .p2align directives, which is typical for LTO output.

This lets us accept an instruction like beq a2,x0,.Label and generate a compressed beqz. This will allow some future simplications to the gcc support, e.g. eliminating some duplicate patterns, and avoiding adding new duplicate patterns, since currently we have to handle signed and equality compares against zero specially.

2019-02-07Arm: Backport hlt to all architectures.Tamar Christina5-1/+79
The software trap instruction HLT that was introduced in Armv8-a is used as the semihosting trap instruction in AArch64. In order to allow systems configured to run AArch64 code to also run AArch32 with semihosting it was decided that AArch32 should also use HLT in the case of the "mixed mode" environment. This requires that HLT also be backported to all earlier architectures. The instruction is in the undefined encoding space earlier architectures but must trigger a semihosting trap [3]. The Arm Architectural Reference Manual [1] doesn't explicitly mention this however this is an explicit requirement in the Semihosting-v2 protocol [2].

2019-01-17Arm: Clean up PE GAS testsuite correct THUMB tests.Tamar Christina9-1/+51
The PE targets don't support mapping symbols and so the disassembler is unable to correctly output thumb instructions when the input was thumb. So for testcases that only have thumb output, I have copied them and skipped the ones for which auto-detection is supposed to work on PE, and added a new one that will force thumb output. This so that the tests still check the mapping symbols. For the tests that switch between thumb and arm in one file I just skip them entirely on PE targets.

2019-01-16S12Z: gas: Fix bug when a symbol name was the single letter 'c'.John Darrington5-4/+32

2019-01-08run_dump_test source in build directoryAlan Modra137-2/+210
Some existing tests build .s and .d files for run_dump_test, using an absolute #source: line in the .d file. This patch changes that scheme a little to instead use "#source: ./..." in .d files rather than "#source: $objdir/...", which is more useful in cases where the .d file is not generated. This allows RX gas test files to be built in the build directory, rather than in a source directory (which might be read-only). binutils/ * testsuite/lib/binutils-common.exp (run_dump_test): Don't prepend $srcdir/$subdir to source file name if it starts with "./". gas/ * testsuite/gas/rx/rx.exp: Create generated test source in current directory. * testsuite/gas/rx/Xtod.d, * testsuite/gas/rx/abs.d, * testsuite/gas/rx/adc.d, * testsuite/gas/rx/add.d, * testsuite/gas/rx/and.d, * testsuite/gas/rx/bclr.d, * testsuite/gas/rx/bcnd.d, * testsuite/gas/rx/bfmov.d, * testsuite/gas/rx/bmcnd.d, * testsuite/gas/rx/bnot.d, * testsuite/gas/rx/bra.d, * testsuite/gas/rx/brk.d, * testsuite/gas/rx/bset.d, * testsuite/gas/rx/bsr.d, * testsuite/gas/rx/btst.d, * testsuite/gas/rx/clrpsw.d, * testsuite/gas/rx/cmp.d, * testsuite/gas/rx/dabs.d, * testsuite/gas/rx/dadd.d, * testsuite/gas/rx/dbt.d, * testsuite/gas/rx/dcmp.d, * testsuite/gas/rx/ddiv.d, * testsuite/gas/rx/div.d, * testsuite/gas/rx/divu.d, * testsuite/gas/rx/dmov.d, * testsuite/gas/rx/dmul.d, * testsuite/gas/rx/dneg.d, * testsuite/gas/rx/dpopm.d, * testsuite/gas/rx/dpushm.d, * testsuite/gas/rx/dround.d, * testsuite/gas/rx/dsqrt.d, * testsuite/gas/rx/dsub.d, * testsuite/gas/rx/dtoX.d, * testsuite/gas/rx/emaca.d, * testsuite/gas/rx/emsba.d, * testsuite/gas/rx/emul.d, * testsuite/gas/rx/emula.d, * testsuite/gas/rx/emulu.d, * testsuite/gas/rx/fadd.d, * testsuite/gas/rx/fcmp.d, * testsuite/gas/rx/fdiv.d, * testsuite/gas/rx/fmul.d, * testsuite/gas/rx/fsqrt.d, * testsuite/gas/rx/fsub.d, * testsuite/gas/rx/ftoi.d, * testsuite/gas/rx/ftou.d, * testsuite/gas/rx/gprel.d, * testsuite/gas/rx/int.d, * testsuite/gas/rx/itof.d, * testsuite/gas/rx/jmp.d, * testsuite/gas/rx/jsr.d, * testsuite/gas/rx/machi.d, * testsuite/gas/rx/maclh.d, * testsuite/gas/rx/maclo.d, * testsuite/gas/rx/max.d, * testsuite/gas/rx/min.d, * testsuite/gas/rx/mov.d, * testsuite/gas/rx/movco.d, * testsuite/gas/rx/movli.d, * testsuite/gas/rx/movu.d, * testsuite/gas/rx/msbhi.d, * testsuite/gas/rx/msblh.d, * testsuite/gas/rx/msblo.d, * testsuite/gas/rx/mul.d, * testsuite/gas/rx/mulhi.d, * testsuite/gas/rx/mullh.d, * testsuite/gas/rx/mullo.d, * testsuite/gas/rx/mvfacgu.d, * testsuite/gas/rx/mvfachi.d, * testsuite/gas/rx/mvfaclo.d, * testsuite/gas/rx/mvfacmi.d, * testsuite/gas/rx/mvfc.d, * testsuite/gas/rx/mvfcp.d, * testsuite/gas/rx/mvfdc.d, * testsuite/gas/rx/mvfdr.d, * testsuite/gas/rx/mvtacgu.d, * testsuite/gas/rx/mvtachi.d, * testsuite/gas/rx/mvtaclo.d, * testsuite/gas/rx/mvtc.d, * testsuite/gas/rx/mvtcp.d, * testsuite/gas/rx/mvtdc.d, * testsuite/gas/rx/neg.d, * testsuite/gas/rx/nop.d, * testsuite/gas/rx/not.d, * testsuite/gas/rx/opecp.d, * testsuite/gas/rx/or.d, * testsuite/gas/rx/pop.d, * testsuite/gas/rx/popc.d, * testsuite/gas/rx/popm.d, * testsuite/gas/rx/push.d, * testsuite/gas/rx/pushc.d, * testsuite/gas/rx/pushm.d, * testsuite/gas/rx/r-bcc.d, * testsuite/gas/rx/r-bra.d, * testsuite/gas/rx/racl.d, * testsuite/gas/rx/racw.d, * testsuite/gas/rx/rdacl.d, * testsuite/gas/rx/rdacw.d, * testsuite/gas/rx/revl.d, * testsuite/gas/rx/revw.d, * testsuite/gas/rx/rmpa.d, * testsuite/gas/rx/rolc.d, * testsuite/gas/rx/rorc.d, * testsuite/gas/rx/rotl.d, * testsuite/gas/rx/rotr.d, * testsuite/gas/rx/round.d, * testsuite/gas/rx/rstr.d, * testsuite/gas/rx/rte.d, * testsuite/gas/rx/rtfi.d, * testsuite/gas/rx/rts.d, * testsuite/gas/rx/rtsd.d, * testsuite/gas/rx/sat.d, * testsuite/gas/rx/satr.d, * testsuite/gas/rx/save.d, * testsuite/gas/rx/sbb.d, * testsuite/gas/rx/sccnd.d, * testsuite/gas/rx/scmpu.d, * testsuite/gas/rx/setpsw.d, * testsuite/gas/rx/shar.d, * testsuite/gas/rx/shll.d, * testsuite/gas/rx/shlr.d, * testsuite/gas/rx/smovb.d, * testsuite/gas/rx/smovf.d, * testsuite/gas/rx/smovu.d, * testsuite/gas/rx/sstr.d, * testsuite/gas/rx/stnz.d, * testsuite/gas/rx/stz.d, * testsuite/gas/rx/sub.d, * testsuite/gas/rx/suntil.d, * testsuite/gas/rx/swhile.d, * testsuite/gas/rx/tst.d, * testsuite/gas/rx/utof.d, * testsuite/gas/rx/wait.d, * testsuite/gas/rx/xchg.d, * testsuite/gas/rx/xor.d: Add #source line. ld/ * testsuite/ld-elf/sec64k.exp: Use . rather than $objdir in generated source file names. * testsuite/ld-m68k/m68k-got.exp: Likewise.
