## 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

## Check case with space between '=' and a value:

# 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: ld.lld -o %t.out --script %t.script %t

## Check we can use an artbitrary expression as a filler.

# RUN: ld.lld -o %t.out --script %t.script %t

## Check case with space between '=' and expression:

# RUN: ld.lld -o %t.out --script %t.script %t
# RUN: llvm-objdump -s %t.out | FileCheck --check-prefix=YES %s

## Check we report an error if expression value is larger than 32-bits.
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } =(0x11 << 32) }" > %t.script
# RUN: not ld.lld -o /dev/null --script %t.script %t 2>&1 | FileCheck --check-prefix=ERR3 %s --implicit-check-not=error:
# ERR3: error: {{.*}}.script:1: filler expression result does not fit 32-bit: 0x1100000000

## Check we report an error if an expression use a symbol.
# RUN: echo "SECTIONS { foo = 0x11; .mysec : { *(.mysec*) } = foo }" > %t.script
# RUN: not ld.lld -o /dev/null %t --script %t.script 2>&1 | FileCheck --check-prefix=ERR4 %s --implicit-check-not=error:

## Check we are able to parse scripts where "/DISCARD/" follows a section fill expression.
# RUN: echo "SECTIONS { .mysec : { *(.mysec*) } =0x1122 /DISCARD/ : { *(.text) } }" > %t.script
