Subject: Bugzilla account? In order to file array-bounds false positive
Date: Sat, 25 Mar 2017 23:36:00 -0000	[thread overview]
Message-ID: <CAJSBJAPmj2RA+TAm-58sgc9gLjFJD2efUMKQPdqJupPWMWNxPA@mail.gmail.com> (raw)

Hi all,

I'd like to file a bug in GCC 6.3 (a weird -Warray-bounds false
positive). Any chance I could get an account created for this email
address?

To prove I'm not a spammer who's full of shit, here's the minimal
repro of the bug:

#include <stdint.h>

    enum {
      ACM0 = 1,
      ACM1
    };

    uint16_t ac[2];
    void foo(uint16_t);

    static inline uint16_t read(int reg)
    {
      switch (reg)
      {
      case ACM0:
      case ACM1:
        return ac[reg - ACM0];
      default:
        return 0;
      }

    }

    void srs(uint8_t reg)
    {
      if (reg < ACM0)
        foo(read(reg));
    }
