Arm: Fix LSB of GOT for Thumb2 only PLT.
When you have a Thumb only PLT then the address in the GOT for PLT0 needs
to
have the Thumb bit set since the instruction used in PLTn to get there is
`ldr.w pc` which is an inter-working instruction:
the PLT sequence in question is
0120 :
120: f240 0c98 movwip, #152; 0x98
124: f2c0 0c01 movtip, #1
128: 44fcadd ip, pc
12a: f8dc f000 ldr.w pc, [ip]
12e: e7fcb.n 12a
Disassembly of section .text:
0130 :
130: b580push{r7, lr}
132: af00add r7, sp, #0
134: f7ff fff4 bl 120
and previously the linker would generate
Hex dump of section '.got':
...
0x000101b8 40010100 1001 @...
Which would make it jump and transition out of thumb mode and crash since
you
only have thumb mode on such cores.
Now it correctly generates
Hex dump of section '.got':
...
0x000101b8 40010100 1101 @...
Thanks to Amol for testing patch and to rgujju for reporting it.
bfd/ChangeLog:
PR ld/16017
* elf32-arm.c (elf32_arm_populate_plt_entry): Set LSB of the PLT0
address in the GOT if in thumb only mode.
ld/ChangeLog:

* testsuite/ld-arm/arm-elf.exp (thumb-plt-got): New.
* testsuite/ld-arm/thumb-plt-got.d: New test.

Since the testsuite lacks a way to preprocess dump files, adjusted copies of the affected dumps are now used on Solaris. Unfortunately, those dumps weren't adapted when the original testcases were changed or other testcases started to differ between non-Solaris and Solaris targets. The following patch fixes that, re-syncing the affected dump files or creating new Solaris-specific ones.

[Bug binutils/25750] GNU as has inconsistent behavior when expanding .macro that takes as input directives with arguments
https://sourceware.org/bugzilla/show_bug.cgi?id=25750 --- Comment #1 from Nick Clifton --- Hi caij, Which version of the binutils are you using for these tests ? When I tried to reproduce the problem using the current development sources I received the message "Error: too many positional arguments" for each invocation of foo. I did however find a variation that worked and did not have any behavioural inconsistencies: .macro foo insn:vararg \insn .endm foo .word (XXX) foo .word 0x1234 foo .section sec1 Using the :vararg suffix to tell the macro processor to use all of the text as a single argument (inside the macro) preserves spaces and results in the output that you would expect.
