- Subject: [PATCH] Fix for immediate AND operation with EXR register of H8S
Hi,
Immediate AND operation with exr register fails with H8 simulator.
When I debug the following program compiled with the command line
"h8300-elf-gcc test.c -ms -g " under gdb simulator it doesn't show the proper result.
/***************************** Start of test.s *****************************/
int main ()
{
asm ("mov #0x07, r0");
asm ("ldc r0l, exr");
asm ("andc #0x89, exr");
return 1;
}
/***************************** End of test.c *****************************/
Please find below patch which fixes the same.
