#12149: Support bit-fields -------------------------------------+------------------------------------- Reporter: | Owner: facundo.dominguez | Type: bug | Status: new Priority: normal | Milestone: Component: hsc2hs | Version: 8.0.1 Keywords: bit-fields | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Having C type like: {{{ typedef struct S { int f0: 1; int f1: 15; } S; }}} and {{{hsc}}} code like {{{ #{peek S, f0} p }}} Causes {{{hsc2hs}}} to fail with {{{ error: attempt to take address of bit-field structure member 'f0' }}} Apparently this is an error from gcc, which cannot provide the address of bit-fields. However, in Haskell we are not interested in the address of the bit-field but in its value. It would be useful to have a way to get and set the values of these fields.
