Consider the case,
.option arch, rv32i
.option norelax
.option arch, +c
.byte 1
.align 2
addi a0, zero, 1
Assembler adds $d for the odd .byte, and then adds $x+arch for the
alignment. Since norelax, riscv_add_odd_padding_symbol will add the
$d and $x for the odd alignment, but accidently remove the $x+arch because
it has the same address as $d. Therefore, we will get the unexpected result
before applying this patch,
.byte 1 # $d
.align 2 # odd alignment, $xrv32ic replaced by $d + $x
After this patch, the expected result should be,
.byte 1 # $d
.align 2 # odd alignment, $xrv32ic replaced by $d + $xrv32ic
gas/
* config/tc-riscv.c (make_mapping_symbol): If we are adding mapping symbol
for odd alignment, then we probably will remove the $x+arch by accidently
when it has the same address of $d. Try to add the removed $x+arch back
after the $d rather than just $x.
(riscv_mapping_state): Updated since parameters of make_mapping_symbol are
changed.
(riscv_add_odd_padding_symbol): Likewise.
(riscv_remove_mapping_symbol): Removed and moved the code into the
riscv_check_mapping_symbols.
(riscv_check_mapping_symbols): Updated.
* testsuite/gas/riscv/mapping-dis.d: Updated and added new testcase.
* testsuite/gas/riscv/mapping-symbols.d: Likewise.
* testsuite/gas/riscv/mapping.s: Likewise.
