           Summary: internal compiler error
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: new bugs

Using recent svn on x86-32 compiling this fragment:

typedef signed char int8_t;
typedef short int int16_t;
typedef int int32_t;
typedef unsigned char uint8_t;
typedef unsigned int uint32_t;
uint32_t g_2 = 8L;
volatile int16_t g_133 = 0x7EAAL;
uint32_t g_139 = 0L;
volatile uint8_t g_160 = 6L;
int32_t func_31 (int16_t p_33, int16_t p_34, int32_t p_35);
int32_t func_97 (uint32_t p_98);
func_97 (uint32_t p_98)
  uint8_t l_190 = 0xFAL;
  int8_t l_163 = 1L;
  for (p_98 = -26; ((g_160) >= -29); (g_160)--)
      int8_t l_192 = 0x85L;
      func_31 (((((l_190 / 1L) - p_98) ^ ((g_139 + p_98) ^ 0xA2D7L))
                && g_2), (((((g_133) && l_192) || p_98) | l_163) > 1L), p_98);

Gives this:

[regehr at babel tmp1]$ llvm-gcc -O0 -S small.c
