Compiler generates incorrect branches inside an interrupt services routine
Version Information
V3.3
Details
In object mode the compiler generates incorrect branches inside an interrupt service routine.
Example:
extern void foo(void);
extern int test(void);
void isr (void)
{
#pragma ghs interrupt
if (test()==1)
{
foo();
}
}
This will generate an endless loop in case result of “test()” is not 1.
Workaround
Use option –noobj to use assembly mode for compilation.
