2015-09-29Don't use the output section size to copy input sectionH.J. Lu1-22/+5
We can't use the output section size to copy input section since --interleave will shrink the output section. Instead, we change bfd_convert_section_contents to return the updated input section size.

2015-09-29Adjust the output section size to skip gap fillsH.J. Lu1-4/+20
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.

2015-08-07objcopy: Improve wildcard matching for symbols with '!' prefix.Andrew Burgess1-4/+4
When using options such as --localize-symbol, --globalize-symbol, etc, along with the --wildcard option, prefixing a symbol name with '!' should provide non-matching behaviour, as example the following example is given in the manual: --wildcard --weaken-symbol !foo --weaken-symbol fo* which should weaken all symbols matching the pattern 'fo*', but not the symbol 'foo'. However, this currently does not work, the current logic will waken all symbols matching the pattern 'fo*' AND all symbols that are not 'foo'. The symbol 'foo' is covered by the first condition, and so is weakened, while, other symbols, for example 'bar' will match the second condition, and so be weakened. This patch adjusts the logic so that a pattern prefixed with '!' specifically DOES NOT apply the relevant change to any matching symbols, instead of applying the change to all non-matching symbols. So this: --weaken-symbol !foo will ensure that the symbol 'foo' is not weakened, but says nothing about symbols that are not 'foo'. As a result, a pattern prefixed with '!' now only makes sense when used alongside a more wide ranging wildcard pattern. This change should make the wildcard matching feature more useful, with no overall loss of functionality. The example given in the manual, weaken all symbols matching 'fo*' except 'foo' can now be achieved, but so too can more complex examples, such as weaken all symbols matching 'fo*' except 'foo', 'foa', and 'fob', like this: --wildcard --weaken-symbol !foo \ --weaken-symbol !foa \ --weaken-symbol !fob \ --weaken-symbol fo* Under the previous scheme, something as symbols as, weaken all symbols except 'foo' could have been achieved with this: --weaken-symbol !foo however, this will no longer work. To achieve the same result under the new scheme this is now required: --weaken-symbol !foo --weaken-symbol * binutils/ChangeLog: * objcopy.c (is_specified_symbol_predicate): Don't stop at first match.

2014-09-08Change pe/coff build-id section name to '.buildid'Jon TURNEY1-2/+2
The section name used to store the build-id on pe/coff is arbitrary, as it's contents should be located using the pe/coff header's DataDirectory debug data entry, not by using the section name. But '.build-id' is not a good choice for that section name, as it is 9 characters long, and hence truncated to 8 characters when --disable-long-section-names is used (which is the default, when producing an executable with no dwarf debug sections, e.g. using ld --strip-all --build-id) This truncation then breaks 'objcopy --only-keep-debug', which does use the section name, due to concerns that keeping an arbitrary section which contains the debug directory is not sensible. binutils/ChangeLog 2014-09-01 Jon TURNEY <jon.turney@dronecode.org.uk> * objcopy.c (is_nondebug_keep_contents_section): Change pe/coff build-id section name from '.build-id' to '.buildid'. ld/ChangeLog 2014-09-01 Jon TURNEY <jon.turney@dronecode.org.uk> * emultempl/pe.em (write_build_id, setup_build_id): Change pe/coff build-id section name from '.build-id' to '.buildid'. * emultempl/pep.em (write_build_id, setup_build_id): Ditto.
