Subject: tree-cfg: Make the verifier returns_twice message translatable
X-Git-Tag: basepoints/gcc-15~205
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8c6f13d2cc1884921e7c532e03786f0344bededd;p=thirdparty%2Fgcc.git

tree-cfg: Make the verifier returns_twice message translatable

While translation of the verifier messages is questionable, that case is
something that ideally should never happen except to gcc developers
and so pressumably English should be fine, we use error etc. APIs and
those imply translatations and some translators translate it.
The following patch adjusts the code such that we don't emit
appel returns_twice est not first dans le bloc de base 33
in French (i.e. 2 English word in the middle of a French message).
Similarly Swedish or Ukrainian.
Note, the German translator did differentiate between these verifier
messages vs. normal user facing and translated it to:
"Interner Fehler: returns_twice call is %s in basic block %d"
so just a German prefix before English message.

	returns_twice diagnostics translatable.
