2018-02-17Add .nop assembler directiveH.J. Lu1-5/+54
Implement the '.nop SIZE[, CONTROL]' assembler directive, which emits SIZE bytes filled with no-op instructions. SIZE is absolute expression. The optional CONTROL byte controls how no-op instructions should be generated. If the comma and @var{control} are omitted, CONTROL is assumed to be zero. For Intel 80386 and AMD x86-64 targets, CONTROL byte specifies the size limit of a single no-op instruction. The valid values of CONTROL byte are between 0 and 8 for 16-bit mode, between 0 and 10 for 32-bit mode, between 0 and 11 for 64-bit mode. When 0 is used, the no-op size limit is set to the maximum supported size. 2 new relax states, rs_space_nop and rs_fill_nop, are added to enum _relax_state, which are similar to rs_space and rs_fill, respectively, but they fill with no-op instructions, instead of a single byte. A target backend must override the default md_generate_nops to generate proper no-op instructions. Otherwise, an error of unimplemented .nop directive will be issued whenever .nop directive is used. * NEWS: Mention .nop directive. * as.h (_relax_state): Add rs_space_nop and rs_fill_nop. * read.c (potable): Add .nop.

2017-09-14PR22127, as segfaults assembling invalid .relocAlan Modra1-1/+1
"sec" gets set to NULL on errors in the offset expression. This patch disables part of the reloc expression processing that needs "sec" valid. I didn't disable the entire reloc expression handling so that errors in the reloc expression are reported even when the offset expression has an error.

2017-03-02GAS: Fix bogus "attempt to move .org backwards" relaxation errorsMaciej W. Rozycki1-4/+5
Fix a commit 6afe8e98a664 ("internal error for backwards .org"), <https://www.sourceware.org/ml/binutils/2008-06/msg00212.html>, GAS regression that caused legitimate code to fail assembly with an "attempt to move .org backwards" error. For example with the `mips-linux' target we get: $ cat org.s .set mips16 la $2, foo .org 0x1000 .align 2 foo: .half 0 $ as -o org.o org.s org.s: Assembler messages: org.s:3: Error: attempt to move .org backwards $ where the location pointer is obviously not moved backwards with `.org'. The cause is positive `stretch' in relaxation due to a PC-relative ADDIU instruction (produced from the LA macro used) getting expanded from 2 to 4 bytes as `foo' is noticed to be out of range for the short encoding. This in turn triggers logic in `relax_segment' which concludes in the processing of an `rs_org' frag produced that the location pointer is moved backwards while in fact only the amount to space forward to the location requested has shrunk, resulting in a negative growth of the frag. Correct the bad logic then and instead verify that the fixed part of an `rs_org' frag has not overrun the location requested, as per the comment already included with the error message: /* Growth may be negative, but variable part of frag cannot have fewer than 0 chars. That is, we can't .org backwards. */ which accurately describes the regression scenario. Move the comment ahead the conditional noted, for clarity. Add generic and MIPS test cases for the `.org' pseudo-op, including the test case discussed though not integrated with the offending commit in particular, adjusted to work across all targets. gas/ * write.c (relax_segment) <rs_org>: Only bail out if the fixed part of the frag has overrun the location requested. * testsuite/gas/all/org-1.d: New test. * testsuite/gas/all/org-2.d: New test. * testsuite/gas/all/org-3.d: New test. * testsuite/gas/all/org-4.d: New test. * testsuite/gas/all/org-5.d: New test. * testsuite/gas/all/org-6.d: New test. * testsuite/gas/all/org-1.l: New stderr output. * testsuite/gas/all/org-2.l: New stderr output. * testsuite/gas/all/org-3.l: New stderr output. * testsuite/gas/all/org-1.s: New test source. * testsuite/gas/all/org-2.s: New test source. * testsuite/gas/all/org-3.s: New test source. * testsuite/gas/all/org-4.s: New test source. * testsuite/gas/all/org-5.s: New test source. * testsuite/gas/all/org-6.s: New test source. * testsuite/gas/all/gas.exp: Run the new tests. * testsuite/gas/mips/org-1.d: New test. * testsuite/gas/mips/org-2.d: New test. * testsuite/gas/mips/org-3.d: New test. * testsuite/gas/mips/org-4.d: New test. * testsuite/gas/mips/org-5.d: New test. * testsuite/gas/mips/org-6.d: New test. * testsuite/gas/mips/org-7.d: New test. * testsuite/gas/mips/org-8.d: New test. * testsuite/gas/mips/org-9.d: New test. * testsuite/gas/mips/org-10.d: New test. * testsuite/gas/mips/org-11.d: New test. * testsuite/gas/mips/org-12.d: New test. * testsuite/gas/mips/org-1.l: New stderr output. * testsuite/gas/mips/org-4.l: New stderr output. * testsuite/gas/mips/org-5.l: New stderr output. * testsuite/gas/mips/org-6.l: New stderr output. * testsuite/gas/mips/org-10.l: New stderr output. * testsuite/gas/mips/org-1.s: New test source. * testsuite/gas/mips/org-2.s: New test source. * testsuite/gas/mips/org-3.s: New test source. * testsuite/gas/mips/org-4.s: New test source. * testsuite/gas/mips/org-5.s: New test source. * testsuite/gas/mips/org-6.s: New test source. * testsuite/gas/mips/org-7.s: New test source. * testsuite/gas/mips/org-8.s: New test source. * testsuite/gas/mips/org-9.s: New test source. * testsuite/gas/mips/org-10.s: New test source. * testsuite/gas/mips/org-11.s: New test source. * testsuite/gas/mips/org-12.s: New test source. * testsuite/gas/mips/mips.exp: Run the new tests.

2016-06-30PR gas/20312: Do not pad sections to alignment on failed assemblyMaciej W. Rozycki1-16/+16
Correct a regression from commit 85024cd8bcb9 ("Run write_object_file after errors") causing unsuccessful assembly, which may be due to any reason, such as supplying a valid source like this: .text .byte 0 .err to terminate with an assertion failure like: test.s: Assembler messages: test.s:3: Error: .err encountered ../as-new: BFD (GNU Binutils) 2.24.51.20140628 internal error, aborting at .../gas/write.c line 608 in size_seg ../as-new: Please report this bug. on targets whose default text section alignment is above 0, typically RISC machines. This is due to an attempt to set last text section's frag alignment to 0, requested from `subsegs_finish_section' where `frag_align_code (alignment, 0)' is called with `alignment' set to 0 rather than the section alignment if `had_errors' has returned true. The call to `subsegs_finish_section' is made from `subsegs_finish' from `write_object_file' at unsuccessful completion, which previously wasn't made. Always set last section's frag alignment from the section alignment then, forcing no section padding instead if completing unsuccessfully, so that in that case alignment padding is still suppressed from any listing generated, fixing assertion failures for these targets: alpha-linuxecoff -FAIL: all pr20312 arm-aout -FAIL: all pr20312 mips-freebsd -FAIL: all pr20312 mips-img-linux -FAIL: all pr20312 mips-linux -FAIL: all pr20312 mips-mti-linux -FAIL: all pr20312 mips-netbsd -FAIL: all pr20312 mips-sgi-irix5 -FAIL: all pr20312 mips-sgi-irix6 -FAIL: all pr20312 mips-vxworks -FAIL: all pr20312 mips64-freebsd -FAIL: all pr20312 mips64-img-linux -FAIL: all pr20312 mips64-linux -FAIL: all pr20312 mips64-mti-linux -FAIL: all pr20312 mips64-openbsd -FAIL: all pr20312 mips64el-freebsd -FAIL: all pr20312 mips64el-img-linux -FAIL: all pr20312 mips64el-linux -FAIL: all pr20312 mips64el-mti-linux -FAIL: all pr20312 mips64el-openbsd -FAIL: all pr20312 mipsel-freebsd -FAIL: all pr20312 mipsel-img-linux -FAIL: all pr20312 mipsel-linux -FAIL: all pr20312 mipsel-mti-linux -FAIL: all pr20312 mipsel-netbsd -FAIL: all pr20312 mipsel-vxworks -FAIL: all pr20312 mipsisa32-linux -FAIL: all pr20312 mipsisa32el-linux -FAIL: all pr20312 mipsisa64-linux -FAIL: all pr20312 mipsisa64el-linux -FAIL: all pr20312 sh-pe -FAIL: all pr20312 sparc-aout -FAIL: all pr20312 gas/ PR gas/20312 * write.c (subsegs_finish_section): Force no section padding to alignment on failed assembly, always set last frag's alignment from section. * testsuite/gas/all/pr20312.l: New list test. * testsuite/gas/all/pr20312.s: New test source. * testsuite/gas/all/gas.exp: Run the new test

The BFD configure option, --enable-elf-stt-common, can't be to used to verify STT_COMMON implementation with the normal binutils build. Instead, this patch removes it from BFD. It adds --elf-stt-common=[no|yes] to ELF assembler/objcopy and adds -z common/-z nocommon to ld. A configure option, --enable-elf-stt-common, is added to gas to specify whether ELF assembler should generate common symbols with the STT_COMMON type by default.

2014-10-18Fix PR17493, attempted output of *GAS `reg' section* symbolAlan Modra1-1/+2
The write.c change is to make gas report an error if reg_section symbols should leak in future. The tc-i386.c change is the real fix. Note that the error isn't the most helpful, "redefined symbol cannot be used on reloc", but I'm not inclined to improve what is really an internal gas error. reg_section symbols shouldn't leak.. gas/ PR 17493 * write.c (adjust_reloc_syms): Don't allow symbols in reg_section to be reduced to reg_section section symbol. * gas/config/tc-i386.c (i386_finalize_immediate): Reject all reg_section immediates. gas/testsuite/ * gas/i386/inval-equ-2.l: Adjust.

2014-06-16Run write_object_file after errorsAlan Modra1-24/+3
This is to fix unitialised memory access when printing listings. Many targets don't initialise parts of insn frags or data frags that have fixups, relying on md_apply_fix to finalise the frag. Which is fine normally, but means we need to run write_object_file after errors, for listings. Otherwise MALLOC_PERTURB_=1 causes errors like: x86_64-linux +FAIL: i386 mpx-inval-1 x86_64-linux +FAIL: i386 inval-equ-1 x86_64-linux +FAIL: i386 x86-64-mpx-inval-1 Running write_object_file after errors requires some tweaking to the testsuite, since we then get extra errors reported from md_apply_fix. gas/ * write.h (subsegs_finish): Delete declaration. * write.c (subsegs_finish): Make static. (write_object_file): Call subsegs_finish from here. Don't print warning and error count here.. * as.c (main): ..do so here instead. Remove dead code for "no object file generated". Split out count strings to better support internationalisation. Don't call subsegs_finish. Tidy setting of "keep_it". Run write_object_file even after errors.

2014-04-09gas TC_PARSE_CONS_EXPRESSION communication with TC_CONS_FIX_NEWAlan Modra1-1/+1
A number of targets pass extra information from TC_PARSE_CONS_EXPRESSION to TC_CONS_FIX_NEW via static variables. That's OK, but not best practice. tc-ppc.c goes further in implementing its own replacement for cons(), because the generic one doesn't allow relocation modifiers on constants.
