Metatype 'int' not recognized in Compiler Specification after Ghidra version upgrade

[v-p-b]

Describe the bug

The following pentry specification:

<pentry minsize="1" maxsize="8" metatype="int">

Works in Ghidra 10, but results in an error in Ghidra 11.0.3.

The error is as follows:

Open failed: ghidra.program.model.lang.CompilerSpecNotFoundException: Exception reading [NAME]/default(file.cspec:123): Unknown type class: int

To Reproduce
Steps to reproduce the behavior:

1. Edit a cspec file to include the offending attribute in a pentry node
2. Open a file in Ghidra 11.0.3 using the modified cspec

Expected behavior

The cspec is parsed and the file is loaded for analysis.

Environment (please complete the following information):

• OS: Debian Linux 11
• Java Version: 17
• Ghidra Version: 11.0.3
• Ghidra Origin: GitHub release

Additional context

I looked at the documentation of the latest release (I uploaded the generated docs here ) and confirmed that the metatype attribute of pentry should accept "int" as a value:

metatype (Optional) Restriction on datatype: unknown, float, int, uint, or ptr

[dev747368]

Yeah, doc is wrong (hasn't been updated since forever). "int" type does not exist.

The code that parsed that value was looser, and used to ignore unknown values, but was changed 11/2023 in commit 1913716.

This clarifies the behavior, thank you!

I suggest to keep this issue open until the documentation is updated (I'll try to open PR, but the linked commit is non-trivial so won't promise anything).
