ld error/warning messages
This patch standardizes messages in ld, to better conform to the GNU coding standard. Besides issues of capitalization and full-stops, I've - Split up help messages for target options, so that adding a new option does not mean loss of translation for all the others. - Embedded tabs have been removed, since a user might have tab stops set at other than 8 char intervals. - Added missing program name (%P). ld isn't the compiler. - Put %F and %X first (and removed %X if %F was present). These can go anywhere, but look silly in the m%Fiddle of a message, and choosing "%P%F:" in some messages but "%F%P:" in others leads to the likelihood of duplication in ld.pot. Besides, the colon belongs with %P. * emulparams/call_nop.sh, * emulparams/cet.sh, * emulparams/elf32mcore.sh, * emultempl/aarch64elf.em * emultempl/aix.em, * emultempl/alphaelf.em, * emultempl/armcoff.em, * emultempl/armelf.em, * emultempl/avrelf.em, * emultempl/beos.em, * emultempl/bfin.em, * emultempl/cr16elf.em, * emultempl/elf32.em, * emultempl/elf-generic.em, * emultempl/hppaelf.em, * emultempl/linux.em, * emultempl/lnk960.em, * emultempl/m68hc1xelf.em, * emultempl/m68kcoff.em, * emultempl/m68kelf.em, * emultempl/metagelf.em, * emultempl/mipself.em, * emultempl/mmix-elfnmmo.em, * emultempl/mmo.em, * emultempl/msp430.em, * emultempl/nds32elf.em, * emultempl/nios2elf.em, * emultempl/pe.em, * emultempl/pep.em, * emultempl/ppc32elf.em, * emultempl/ppc64elf.em, * emultempl/scoreelf.em, * emultempl/sh64elf.em, * emultempl/spuelf.em, * emultempl/sunos.em, * emultempl/tic6xdsbt.em, * emultempl/ticoff.em, * emultempl/v850elf.em, * emultempl/vms.em, * emultempl/vxworks.em, * emultempl/xtensaelf.em, * ldcref.c, * ldctor.c, * ldexp.c, * ldfile.c, * ldgram.y, * ldlang.c, * ldmain.c, * ldmisc.c, * ldwrite.c, * lexsup.c, * mri.c, * pe-dll.c, * plugin.c: Standardize error/warning messages. * testsuite/ld-arc/jli-overflow.err, * testsuite/ld-arm/cmse-implib-errors.out, * testsuite/ld-arm/cmse-new-earlier-later-implib.out, * testsuite/ld-arm/cmse-new-implib-not-sg-in-implib.out, * testsuite/ld-arm/cmse-new-wrong-implib.out, * testsuite/ld-arm/cmse-veneers-no-gnu_sgstubs.out, * testsuite/ld-arm/cmse-veneers-wrong-entryfct.out, * testsuite/ld-arm/vxworks1-static.d, * testsuite/ld-cris/tls-err-20x.d, * testsuite/ld-cris/tls-err-29.d, * testsuite/ld-cris/tls-err-31.d, * testsuite/ld-cris/tls-err-33.d, * testsuite/ld-cris/tls-err-35.d, * testsuite/ld-cris/tls-err-37.d, * testsuite/ld-cris/tls-err-39.d, * testsuite/ld-cris/tls-err-41.d, * testsuite/ld-cris/tls-err-43.d, * testsuite/ld-cris/tls-err-45.d, * testsuite/ld-cris/tls-err-47.d, * testsuite/ld-cris/tls-err-49.d, * testsuite/ld-cris/tls-err-51.d, * testsuite/ld-cris/tls-err-67.d, * testsuite/ld-elf/dwarf2.err, * testsuite/ld-elf/dwarf3.err, * testsuite/ld-elf/orphan-5.l, * testsuite/ld-elf/orphan-6.l, * testsuite/ld-i386/vxworks1-static.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic-micromips.d, * testsuite/ld-mips-elf/bal-jalx-pic-n32.d, * testsuite/ld-mips-elf/bal-jalx-pic-n64.d, * testsuite/ld-mips-elf/bal-jalx-pic.d, * testsuite/ld-mips-elf/jal-global-overflow-1.d, * testsuite/ld-mips-elf/jal-local-overflow-1.d, * testsuite/ld-mips-elf/mode-change-error-1.d, * testsuite/ld-mips-elf/unaligned-branch-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-2.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-ignore-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-micromips.d, * testsuite/ld-mips-elf/unaligned-branch-mips16.d, * testsuite/ld-mips-elf/unaligned-branch-r6-1.d, * testsuite/ld-mips-elf/unaligned-branch-r6-2.d, * testsuite/ld-mips-elf/unaligned-branch.d, * testsuite/ld-mips-elf/unaligned-jalx-1.d, * testsuite/ld-mips-elf/unaligned-jalx-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-3.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-addend-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jalx-micromips-1.d, * testsuite/ld-mips-elf/unaligned-jalx-mips16-1.d, * testsuite/ld-mips-elf/unaligned-jump-micromips.d, * testsuite/ld-mips-elf/unaligned-jump-mips16.d, * testsuite/ld-mips-elf/unaligned-jump.d, * testsuite/ld-mips-elf/unaligned-ldpc-1.d, * testsuite/ld-mips-elf/unaligned-lwpc-1.d, * testsuite/ld-mips-elf/undefined.d, * testsuite/ld-mips-elf/vxworks1-static.d, * testsuite/ld-mmix/bpo-20.d, * testsuite/ld-mmix/bpo-20m.d, * testsuite/ld-mmix/bpo-7.d, * testsuite/ld-mmix/bpo-7m.d, * testsuite/ld-mmix/bpo-8.d, * testsuite/ld-mmix/bpo-8m.d, * testsuite/ld-mmix/greg-17.d, * testsuite/ld-mmix/greg-18.d, * testsuite/ld-mmix/greg-8.d, * testsuite/ld-mmix/greg-9.d, * testsuite/ld-plugin/plugin-14.d, * testsuite/ld-plugin/plugin-15.d, * testsuite/ld-plugin/plugin-16.d, * testsuite/ld-plugin/plugin-20.d, * testsuite/ld-plugin/plugin-21.d, * testsuite/ld-plugin/plugin-22.d, * testsuite/ld-plugin/plugin-23.d, * testsuite/ld-plugin/plugin-6.d, * testsuite/ld-plugin/plugin-7.d, * testsuite/ld-plugin/plugin-8.d, * testsuite/ld-powerpc/aix-weak-3-32.d, * testsuite/ld-powerpc/aix-weak-3-64.d, * testsuite/ld-powerpc/vxworks1-static.d, * testsuite/ld-sh/vxworks1-static.d, * testsuite/ld-sparc/vxworks1-static.d, * testsuite/ld-undefined/undefined.exp, * testsuite/ld-x86-64/pie1.d: Update for changed errors and warnings. * testsuite/ld-elf/warn1.d, * testsuite/ld-elf/warn2.d: Correct regex. |

MIPS/BFD: Enable local R_MIPS_26 overflow detection
The original MIPS SVR4 psABI defines the calculation for the R_MIPS_26
relocation in a complex way, as follows[1]:
Name Value Field Symbol Calculation
R_MIPS_26 4 T-targ26 local (((A << 2) | \
(P & 0xf0000000)) + S) >> 2
4 T-targ26 external (sign-extend(A << 2) + S) >> 2
This is further clarified, by correcting typos (already applied in the
excerpt above) in the 64-bit psABI extension[2]. A note is included in
both documents to specify that for the purpose of relocation processing
a local symbol is one with binding STB_LOCAL and type STT_SECTION, and
otherwise, a symbol is external.
We have both calculations implemented for the R_MIPS_26 relocation, and
by extension also for the R_MIPS16_26 and R_MICROMIPS_26_S1 relocations,
from now on collectively called jump relocations. However our code uses
a different condition to tell local and external symbols apart, that is
it only checks for the STB_LOCAL binding and ignores the symbol type,
however for REL relocations only. The external calculation is used for
all RELA jump relocations.
In reality the difference matters for jump relocations referring local
MIPS16 and, as from recent commit
