Description:   Last confirmed: Opened: 2008-11-20 16:13 
New test gcc.dg/torture/pr37868.c fails for -O[0123s] with:

/usr/local/avrdev/gcc/gcc/gcc/testsuite/gcc.dg/torture/pr37868.c:8: error:
width of 'a' exceeds its type

/usr/local/avrdev/gcc/gcc/gcc/testsuite/gcc.dg/torture/pr37868.c:9: error:
width of 'b' exceeds its type


The test contains these declarations:
struct X {
  unsigned char pad : 4;
  unsigned int a : 32;
  unsigned int b : 24;
  unsigned int c : 6;
} __attribute__((packed));

An int on the AVR is 16-bits, hence the width of 'a' and 'b' exceed their type.

        * gcc.dg/torture/pr37868.c: New testcase.
        * gcc.c-torture/execute/pr38048-1.c: Likewise.
        * gcc.c-torture/execute/pr38048-2.c: Likewise.

gcc.dg/torture/pr37868.c should report the error..This is the positive test
case for avr-gcc as the size of int = 16 bits,and in the struct X int bit field
width is >16
