x86: Add i386 PE big-object support
The 64-bit version of binutils got support for the PE COFF BIG OBJ format a
couple of years ago. The BIG OBJ format is a slightly different COFF format
which extends the size of the number of section field in the header from a
uint16_t to a uint32_t and so greatly increases the number of sections allowed.
However the 32-bit version of bfd never got support for this. The GHC Haskell
compiler generates a great deal of symbols due to it's use of
-ffunction-sections and -fdata-sections.
This meant that we could not build the 32-bit version of the GHC Compiler for
many releases now as binutils didn't have this support.
This patch adds the support to the 32-bit port of binutils as well and also does
come cleanup in the code.
bfd/ChangeLog:
* coff-i386.c (COFF_WITH_PE_BIGOBJ): New.
* coff-x86_64.c (COFF_WITH_PE_BIGOBJ): New.
* config.bfd (targ_selvecs): Rename x86_64_pe_be_vec
to x86_64_pe_big_vec as it not a big-endian format.
(vec i386_pe_big_vec): New.
* configure.ac: Likewise.
* targets.c: Likewise.
* configure: Regenerate.
* pe-i386.c (TARGET_SYM_BIG, TARGET_NAME_BIG,
COFF_WITH_PE_BIGOBJ): New.
* pe-x86_64.c (TARGET_SYM_BIG, TARGET_NAME_BIG):
New.
(x86_64_pe_be_vec): Moved.
gas/ChangeLog:
* NEWS: Add news entry for big-obj.
* config/tc-i386.c (i386_target_format): Support new format.
* doc/c-i386.texi: Add i386 support.
* testsuite/gas/pe/big-obj.d: Rename test to not be x64 specific.
* testsuite/gas/pe/pe.exp (big-obj): Make test run on i386 as well.
ld/ChangeLog:
* pe-dll.c (pe_detail_list): Add pe-bigobj-i386.
