[PATCH] mostly unify readonly_error in C and C++ front-ends
- From: Nathan Froyd <froydnj at codesourcery dot com>
- To: gcc-patches at gcc dot gnu dot org

- Subject: [PATCH] mostly unify readonly_error in C and C++ front-ends
This patch introduces a common readonly_error function that can be used
by the C and C++ front-ends along with associated tweaks to make it work
right. Notably, the C++-specific readonly_error_kind goes away,
subsumed by lvalue_use, and the C++ readonly_error function is renamed
to cp_readonly_error to handle a few C++-specific cases.
I thought the C++ wording was better in most cases, though the "used as
`asm' output" phrasing that the C front-end uses is preferable to "(via
'asm' output)", I think. I also think the greater number of cases
handled by the C++ front-end and the more precise wording will be useful
in the C front-end.
Tested on x86_64-unknown-linux-gnu. OK to commit?
