Binutils is supposed to use tabs.

2017-11-13PE: don't corrupt section flags when linking from ELF objectsJan Beulich
Linking EFI executables from ELF object files can result in corrupted COFF section flags if the section's alignment is too high. Issue a diagnostic in that case, erroring out if this is not a final link, and make sure only in-range values get written to the output image. While doing this also make tic80 use the generic alignment macros instead of custom #ifdef-ary. No testsuite regressions for the range of COFF/PE targets that actually cross-build in the first place on x86-64-linux.

2017-06-16Rewrite __start and __stop symbol handlingAlan Modra
This arranges for __start and __stop symbols to be defined before garbage collection, for all target formats. That should allow the COFF and PE --gc-sections to keep a singleton orphan input section, a feature lost by 2017-06-13 commit cbd0eecf26. The fancier ELF treatment of keeping all input sections associated with a __start or __stop symbol, from 2015-10-23 commit 1cce69b9dc, is retained. .startof. and .sizeof. symbols are deliberately not defined before garbage collection, so these won't affect garbage collection of sections. The patch also ensures __start, __stop, .startof. and .sizeof. symbols are defined before target size_dynamic_sections is called, albeit with a preliminary value, so that target code doesn't need to cope with a symbol changing from undefined at size_dynamic_sections to defined at relocate_section. Also, a number of problems with the testcases have been fixed.

2017-05-10bfd: new BFD target entry point _bfd_set_reloc.Jose E. Marchesi
This patch adds a new entry point to the BFD_JUMP_TABLE_RELOCS. The previous common implementation `bfd_set_reloc', in bfd/bfd.c, has been moved to bfd/reloc.c with the name `_bfd_generic_set_reloc', and all BFD targets has been adapted to use it. This patch doesn't introduce any change on functionality, but prepares the ground for further work. bfd/ChangeLog: 2017-05-10 Jose E. Marchesi <jose.marchesi@oracle.com> * targets.c (BFD_JUMP_TABLE_RELOCS): Add NAME##_set_reloc.

2014-11-11Avoid coff OOMAlan Modra
bfd_zalloc/bfd_zmalloc to fix uninitialized memory reads is too big a hammer, when the size allocated depends on user input. A typical bfd_alloc, bfd_seek, bfd_bread sequence will give an error or warning at the point the file read fails when some enormous item as described by headers is not actually present in the file. Nice operating system allow memory overcommit. But not if you write to the memory. So bfd_zalloc can cause an OOM, thrashing, or system hangs. The patch also fixes a recently introduced endless loop on bad input. PR binutils/17512 * coffcode.h (coff_slurp_line_table): Don't bfd_zalloc, just memset the particular bits we need.

2014-06-13Don't call bfd_link_hash_table_freeAlan Modra
Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.
