ld/ARM: Increase maximum page size to 64kB
...
Increase the maximum page size to 64kB and align the TEXT_START_ADDR
to a 64kB boundary. This brings AArch32 in line with AArch64 and
improves compatability under certain conditions.
bfd/ChangeLog:
2014-07-08 Will Newton <will.newton@linaro.org>
* elf32-arm.c (ELF_MAXPAGESIZE): Increase the default
value to 64kB and remove custom setting for NaCl.
ld/ChangeLog:
2014-07-08 Will Newton <will.newton@linaro.org>
* emulparams/armelf_linux.sh (TEXT_START_ADDR): Increase
alignment to 64kB boundary.
ld/testsuite/ChangeLog:
2014-07-08 Will Newton <will.newton@linaro.org>
* ld-arm/arm-lib.ld: Increase MAXPAGESIZE value to
match bfd.
* ld-arm/cortex-a8-fix-bl-rel-plt.d: Update offsets to
