I found this when tried to link linux kernel with LLD: https://github.com/torvalds/linux/blob/master/arch/x86/entry/vdso/vdso-layout.lds.S#L86 Output section command can have optional comma at the end: .text : { *(.text*) } :text =0x90909090, It was documented about 3 years ago for binutils: https://sourceware.org/ml/binutils/2014-04/msg00045.html Differential revision: https://reviews.llvm.org/D28803 llvm-svn: 292225

# REQUIRES: x86
|
|
# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux %s -o %t
|
|
|
|
## Check that padding value works:
|
|
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } =0x1122 }" > %t.script
|
|
# RUN: ld.lld -o %t.out --script %t.script %t
|
|
# RUN: llvm-objdump -s %t.out | FileCheck -check-prefix=YES %s
|
|
# YES: 66001122 00001122 00001122 00001122
|
|
|
|
## Confirming that address was correct:
|
|
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } =0x99887766 }" > %t.script
|
|
# RUN: ld.lld -o %t.out --script %t.script %t
|
|
# RUN: llvm-objdump -s %t.out | FileCheck -check-prefix=YES2 %s
|
|
# YES2: 66887766 99887766 99887766 99887766
|
|
|
|
## Default padding value is 0x00:
|
|
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } }" > %t.script
|
|
# RUN: ld.lld -o %t.out --script %t.script %t
|
|
# RUN: llvm-objdump -s %t.out | FileCheck -check-prefix=NO %s
|
|
# NO: 66000000 00000000 00000000 00000000
|
|
|
|
## Decimal value.
|
|
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } =777 }" > %t.script
|
|
# RUN: ld.lld -o %t.out --script %t.script %t
|
|
# RUN: llvm-objdump -s %t.out | FileCheck -check-prefix=DEC %s
|
|
# DEC: 66000309 00000309 00000309 00000309
|
|
|
|
## Invalid hex value:
|
|
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } =0x99XX }" > %t.script
|
|
# RUN: not ld.lld -o %t.out --script %t.script %t 2>&1 \
|
|
# RUN: | FileCheck --check-prefix=ERR2 %s
|
|
# ERR2: invalid filler expression: 0x99XX
|
|
|
|
## Check case with space between '=' and expression:
|
|
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } = 0x1122 }" > %t.script
|
|
# RUN: ld.lld -o %t.out --script %t.script %t
|
|
# RUN: llvm-objdump -s %t.out | FileCheck -check-prefix=YES %s
|
|
|
|
## Check case with optional comma following output section command:
|
|
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } =0x1122, .a : { *(.a*) } }" > %t.script
|
|
# RUN: ld.lld -o %t.out --script %t.script %t
|
|
# RUN: llvm-objdump -s %t.out | FileCheck -check-prefix=YES %s
