>Environment:
System: Linux kiste 2.4.18 #8 Sat Mar 9 15:33:15 CET 2002 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../gcc/configure --enable-shared --disable-nls --enable-threads=posix --enable-languages=c,c++,f77,objc
>Description:
The following source code, extracted from FTensor, is rejected by gcc
3.1. KCC supports this feature, an array of restricted pointers. Is
this a gcc flaw or a KCC extension?
>How-To-Repeat:
source code restrict.C
struct A
{
int* __restrict__ data[10];
};
g++ -v -c restrict.C -W -Wall
Reading specs from /usr/local/lib/gcc-lib/i686-pc-linux-gnu/3.1/specs
