Hi DJ,
Compiling a program with one of the real RL78 registers marked as
call-used (eg via -fcall-used-ax), can trigger an internal compiler
error. Although modifying the ABI in this way may not be a good idea,
it is still wrong that the compiler generates an ICE.
The patch below
Hi DJ,
Compiling this test case with the RL78 toolchain results in an ICE:
unsigned char g_X;
unsigned char g_Y;
const __far unsigned char TabA[2][2] = { { 3, 0 }, { 4, 5 } };
void main (void) { g_X = 1; g_Y = TabA[g_X][g_X]; }
The problem appears to be that GCC will create
