Bug ID: 24129
Summary: [RISCV] .align with fill only partially fills
Product: binutils
Version: 2.33 (HEAD)
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: asb at lowrisc dot org
Target Milestone: ---
$ ./riscv32-unknown-elf-as --version | head -n 1
GNU assembler (GNU Binutils) 2.32.51.20190124
$ cat t.s
slli s1, s1, 0x14
.align 3, 2
slli s1, s1, 0x14
.section data
.word 1234
.align 3, 2
.word 1234
$ ./riscv32-unknown-elf-as -march=rv32imc -mno-arch-attr -mno-relax t.s
$ ./riscv32-unknown-elf-objdump -Dr a.out
a.out: file format elf32-littleriscv
Disassembly of section .text:
00000000 <.text>:
0: 04d2 slli s1,s1,0x14
2: 0202 c.slli64 tp
4: 0202 c.slli64 tp
6: 0202 c.slli64 tp
8: 04d2 slli s1,s1,0x14
a: 0001 nop
c: 00000013 nop
Disassembly of section data:
00000000 <data>:
0: 04d2 slli s1,s1,0x14
2: 0000 unimp
4: 0202 c.slli64 tp
6: 0202 c.slli64 tp
8: 04d2 slli s1,s1,0x14
...
As you can see, the fill in the data section is incomplete (should be 0x02
throughout the padding). This issue occurs regardless regardless of whether
relaxation is enabled/disabled.
