| ## 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 |
| # RUN: llvm-readobj -S %t.nonote | FileCheck %s --check-prefix=NONOTE --implicit-check-not='Name: .note' |
