>Description:
The program below fails to compile with GCC 3.2 (native compiler under x86 GNU/Linux) and GCC 3.1.1 (mingw32 cross compiler under SPARC Solaris).
Changes for GCC 3.2.2 does not seem to mention this problem.
Native GCC 3.2 compiler under x86 GNU/Linux yields:
g++ -O0 -march=i668 internal.cpp
internal.cpp: In function `int main()':
internal.cpp:6: Internal compiler error in emit_move_insn, at expr.c:2769
GCC 3.1.1 cross compiler for mingw32 target under SPARC Solaris yields:
i386-pc-mingw32-gcc -O0 -march=i686 internal.cpp
internal.cpp: In function `int main()':
internal.cpp:6: Internal compiler error in emit_move_insn, at expr.c:
2769
The program only fails for GCC 3.1.1 if -march=i686 is set!
void myFunction(short) {
}
int main() {
long double temp = 1;
myFunction(static_cast<unsigned long long>(temp)); // ERR
return 0;
}
