## Check that yaml2obj limits the output size by default to 10 MB.
## Check it is possible to change this limit using the
## --max-size command line option.
## One of the often cases to reach the limit is to create a section with a
## large portion of data. Check this case is handled properly.
## 0x9FFEC0 = 0xA00000 (10 MB) - sizeof(Elf_Ehdr) - sizeof(Elf_Shdr) * 4.
# RUN: yaml2obj %s -DSIZE=0x9FFEC0 --docnum=1 -o /dev/null 2>&1
# RUN: not yaml2obj %s -DSIZE=0x9FFEC1 --docnum=1 -o /dev/null 2>&1 | \
# RUN: FileCheck %s --check-prefix=ERROR
# ERROR: error: the desired output size is greater than permitted. Use the --max-size option to change the limit
## We use 0xA00008 instead of 0xA00001 here because the section header table
## offset is aligned to 8 bytes, so we need to request 7 more bytes for it.
