## For --gc-sections, group members are retained or discarded as a unit.
|
|
## However, discarding a section via /DISCARD/ should not discard other members
|
|
## within the group. This is compatible with GNU ld.

|
|
# RUN: llvm-mc -filetype=obj -triple=armv7a-none-linux-gnueabi %s -o %t.o
|

|
|
## We can discard .ARM.exidx* in a group.
|
|
# RUN: echo 'SECTIONS { /DISCARD/ : { *(.ARM.exidx*) }}' > %t.noarm.script
|
|
# RUN: ld.lld %t.o --gc-sections -T %t.noarm.script -o %t.noarm
|

# RUN: llvm-readobj -S %t.noarm | FileCheck %s --check-prefix=NOARM --implicit-check-not='Name: .ARM.exidx'

# NOARM: Name: .text

# NOARM: Name: .note._start

## Another example, we can discard SHT_NOTE in a group.

# RUN: echo 'SECTIONS { /DISCARD/ : { *(.note*) }}' > %t.nonote.script

# RUN: ld.lld %t.o --gc-sections -T %t.nonote.script -o %t.nonote
