| ## 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. |
| # RUN: yaml2obj %s -DSIZE=0x9FFEC1 --docnum=1 --max-size=0xA00008 -o /dev/null |
