## 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.

|
## 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.
