[cfe-dev] Patch for union bit field crash

[Sachin.Punyani at microchip.com]

Hi,

 

Please consider the case.

 

union  u {

   unsigned i : 3

}uvar;

 

Some more information

----------------------------------

Size of int - 2 bytes 

Alignment of int - 1 byte

Size of char - 1 byte

Alignment of char - 1 byte

 

The field size is 3 and it should be accommodated in char. However there
is an assertion failure in clang. (Options : --emit-llvm-bc
--triple=pic16 ; the above information for size and alignment is from
PIC16)

 

Please find the patch attached for this fix. Please provide your
feedback on this. 

 

Regards

Sachin
