When the following code is compiled
---------------------
# 1 "<built-in>"
# 1 "<command line>"
# 1 "test.c"
extern void DisplayNumber (unsigned long);
unsigned long ReadNumber ()
{
return 8L;
}
void test_a (void)
{
unsigned long tmp;
tmp = (ReadNumber() & 0x00ff0000L) >> 16;
DisplayNumber (tmp);
}
------------------------------------------
The code generated for the test_a function is incorrect.
The compiler is mainline CVS built on 20031127
Compiler command line was
h8300-hitachi-elf-gcc -v --save-temps -Wall -I include -Wa,-a=test.lst -
gstabs -O1 -finline -c test.c
Compiler was configured as
