Date: Thu, 16 Nov 2000 21:23:28 +0000 [thread overview]
Message-ID: <E13wWZR-000Gm6-0A@finch-post-10.mail.demon.net> (raw)
stephen.parker@pitechnology.com reports a misleading C compiler error message from:
struct S {
int const *p;
};
The underlying cause is that the compiler expects const/volatile keywords before
other simple type names in a structure/union element declarator (but nowhere else) --
in the same context "const int *p" is considered acceptable.
Is this a deliberate choice or an oversight? If the latter, a simple correction
is to change the grammar as follows:
/sys/src/cmd/cc/cc.y:216 c cc.y:216
< etlist
---
> tlist
/sys/src/cmd/cc/cc.y:221 c cc.y:221
< | edecl etlist
---
> | edecl tlist
The definitions of etlist, etypes and tnlist then become redundant and can be
pruned from cc.y as well.
