2015-09-29Adjust the output section size to skip gap fillsH.J. Lu4-0/+34
In objcopy, copy_object calls copy_section to copy contents of input section to output section. When --gap-fill= is used, objcopy extends the size of output sectios to fill gaps between output sections with gap fills. In this case, we adjust the output section size to skip gap files to avoid reading beypond the input section buffer before calling copy_section and restore the output section size after input sections have been copied. binutils/ PR binutils/19005 * objcopy.c (copy_object): Adjust the output section size to skip gap fills between sections when copying from input sections to output sections. ld/testsuite/ PR binutils/19005 * ld-elf/pr19005.d: New file. * ld-elf/pr19005.s: Likewise. * ld-elf/pr19005.t: Likewise.

This fixes two problems. First, the --sysroot option wasn't available with a ld configured without --with-sysroot, a historical accident.

2015-09-18Delay converting linker script defined symbols from absoluteAlan Modra13-8/+142
Giving linker script symbols defined outside of output sections a section-relative value early, leads to them being used in expressions as if they were defined inside an output section.

2015-09-07ld: Fix failures in new orphan handling tests.Andrew Burgess4-7/+16
The new orphan handling tests added in commit c005eb9 fail on a range of targets. Some of the failures were fixed in commit e32aa93 but not all. This commit should address the remaining failures. Update results to account for orphan sections being placed in different orders, and for other, target specific sections, being discarded. ld/testsuite/ChangeLog: * ld-elf/orphan-7.map: Allow for other discarded sections. * ld-elf/orphan-8.map: Updated to allow for different section ordering on different targets. * ld-elf/orphan.ld: Place .sbss section.

2015-09-04ld: Extend options for altering orphan handling behaviour.Andrew Burgess18-65/+195
Replace the options --warn-orphan and --no-warn-orphan with a single option --orphan-handling=MODE, where mode can be place, warn, error, and discard. Mode 'place' is the default, and is the current behaviour, placing the orphan section into a suitable output section. Mode 'warn' is the same as '--warn-orphan'. The orphan is also placed using the same algorithm as for 'place'. Mode 'error' is the same as '--warn-orphan' and '--fatal-warnings'. Mode 'discard' assigns all output sections to the /DISCARD/ section. ld/ChangeLog: * ld.h (enum orphan_handling_enum): New. (ld_config_type): Remove warn_orphan, add orphan_handling. * ldemul.c (ldemul_place_orphan): Remove warning about orphan sections. * ldlang.c (ldlang_place_orphan): New function. (lang_place_orphans): Call ldlang_place_orphan. * ldlex.h (enum option_values): Remove OPTION_WARN_ORPHAN and OPTION_NO_WARN_ORPHAN, add OPTION_ORPHAN_HANDLING. * lexsup.c (ld_options): Remove 'warn-orphan' and 'no-warn-orphan', add 'orphan-handling'. (parse_args): Remove handling for OPTION_WARN_ORPHAN and OPTION_NO_WARN_ORPHAN, add handling for OPTION_ORPHAN_HANDLING. * NEWS: Replace text about --warn-orphan with --orphan-handling. * ld.texinfo (Options): Remove --warn-orphan entry and add entry on --orphan-handling. (Orphan Sections): Add reference to relevant command line options. ld/testsuite/ChangeLog: * ld-elf/elf.exp: Switch to rely on run_dump_test. * ld-elf/orphan-5.l: Update expected output. * ld-elf/orphan-5.d: New file. * ld-elf/orphan-6.d: New file. * ld-elf/orphan-6.l: New file. * ld-elf/orphan-7.d: New file. * ld-elf/orphan-7.map: New file. * ld-elf/orphan-8.d: New file. * ld-elf/orphan-8.map: New file.
