--- Comment #2 from Tobias Burnus <burnus at gcc dot gnu.org> ---
This PR might have the same reason as PR60567.

Namely, your GCC has not been compiled on a system with working linker plugin -
and thus, lto1 is not invoked with -fresolution=.

Try compiling with "-fuse-linker-plugin" - if that gives an error, try a GCC
which has been configured with --with-plugin-ld= pointing to a newer Binutils -
2.21 or newer. If that helps, it is a duplicate of PR60567.

If it doesn't help: Create a reduced test case as described at
http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction#Reducing_LTO_bugs

I was able to (manually) reduce the test to 

g++  -r -nostdlib  src/.libs/liblog4cplus_la-rootlogger.ii -flto -o
.libs/cyglog4cplus-1-2-2.dll

The preprocessed file is attached compressed.

Or we might produce a call to __builtin_unreachable (we already do
that in ipa_get_indirect_edge_target_1 in similar cases) or
__builtin_abort.  Tough decision, although I'll probably go for
__builtin_unreachable, for the sake of consistency.

Oops! All of this should have gone to PR 56963 instead.

BTW, the current version with which I have reduced the test case is this:

            Bug ID: 60614
           Summary: -Wtype-limits fails to warn on unsigned bitfields
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3

          Assignee: unassigned at gcc dot gnu.org

This is possibly related to #54787, but with a different case.

After finding a bug in code compiled with avr-gcc, I created this test case, as
no warning was issued when I expected it. The following test case is tested on:

$ gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-unknown-linux-gnu/4.8.2/lto-wrapper

--disable-multilib --disable-werror --enable-checking=release
Thread model: posix
gcc version 4.8.2 20140206 (prerelease) (GCC)

Test case:
#include <stdio.h>

struct {
    unsigned char field1 :3;
    unsigned char field2 :5;
} teststruct;

int main ( void ) {

    unsigned char test;

    if (teststruct.field1 < 0) //issues no warning
        printf("Field1 was negative\n");

    if (test < 0) //issues warning
        printf("Test was negative\n");

    return 0;
}


// Compilation:
$ gcc -Wall -Wextra test.c -o test
test.c: In function ‘main’:
test.c:17:2: warning: comparison is always false due to limited range of data
type [-Wtype-limits]
  if (test < 0)
  ^


==
The warning is not issued on test for negative unsigned bitfield as I expected
it.

--- Comment #4 from Martin Jambor <jamborm at gcc dot gnu.org> ---
This is what I'm about to bootstrap and test and then try with Mozilla
Firefox.

It might be worthwhile to report the error in the library from which
the testcase is derived.  You can even try and build and test the
library with this patch but with BUILT_IN_UNREACHABLE replaced with
BUILT_IN_ABORT to track the issue.

Closing as duplicate in the attempt to weed out old bugs that lack reproducers.
