[Bug target/26350] New: ICE in extract_insn, at recog.c:2084, -fPIC -mlong-double-128

[rguenth at gcc dot gnu dot org]

We ICE building hercules for powerpc32.  Reduced testcase, build with
-O2 -fPIC -mlong-double-128:


  typedef int int32_t __attribute__ ((__mode__ (__SI__)));
  typedef unsigned char uint8_t;
  typedef unsigned int uint32_t;
  typedef struct REGS REGS;
  typedef union { uint32_t F; } FW;
  typedef union { struct { FW L; } F; } DW;
  typedef struct _PSW {
          DW ia;
  } PSW;
  struct REGS {
          PSW psw;
          DW cr[16];
  };
  struct ebfp {
     long double v;
  };
void ( s390_convert_fix32_to_bfp_ext_reg) (REGS *regs)
{
      struct ebfp op1;
      int32_t op2;
 ((regs))->psw.ia.F.L.F += (4);
 if(!((regs)->cr[(0)].F.L.F & 0x00040000))
   op1.v = (long double)op2;
 put_ebfp(&op1);
}
