             Bug #: 55934

           Summary: [4.8 Regression] LRA inline asm error recovery

    Classification: Unclassified

           Product: gcc

           Version: 4.8.0

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: inline-asm

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: ja...@gcc.gnu.org





_Complex float

foo (void)

{

  _Complex float x;

  __asm ("" : "=x" (x)); /* { dg-error "impossible register constraint" } */

  return x;

}



on x86_64 used to ICE since the introduction of LRA (before that it has been

just issuing error on the asm).  Starting with

http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=193871

this got fixed, but already (guess) starting with

http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=193901

it issues both the expected error and also ICE after it.
