llvm/test/tools/llvm-readobj/ELF/grouped.test

## In this test we check that short command line options can be grouped.

## Check grouped options produce identical output to when not grouped.
# RUN: yaml2obj %s -o %t.o
# RUN: llvm-readelf -aeWhSrnudlVgIs %t.o > %t.grouped
# RUN: llvm-readelf -a -e -W -h -S -r -n -u -d -l -V -g -I -s %t.o > %t.not-grouped
# RUN: cmp %t.grouped %t.not-grouped
# RUN: FileCheck /dev/null --input-file %t.grouped --implicit-check-not=error:

## Check that the output without -a (--all) option is the same. We do it
## to verify that each of the options is handled, and not just the first
## one nor just -a, which triggers all other options.
# RUN: llvm-readelf -eWhSrnudlVgIs %t.o > %t.grouped.no.a
# RUN: cmp %t.grouped %t.grouped.no.a

## -e (--headers) is equivalent to setting --file-headers (-h),
## --program-headers (-l) and --section-headers (-S).
## Check that the output without -e is equal to the output with it.
## We do not use -a in this test either.
# RUN: llvm-readelf -WhSrnudlVgIs %t.o > %t.grouped.no.ae
# RUN: cmp %t.grouped %t.grouped.no.ae

## An arbitrary YAML description that triggers an output for each of
## the short option from the test sequence.
