[Bug middle-end/41248] New: Assertion at 2910 of cfgexpand.c (expand_debug_locations)

[sje at cup dot hp dot com]

On ia64-hp-hpux11.23, which supports a 32 and 64 bit mode, I get an assertion
failure during bootstrap.  This is with version 151382.

insn is:

(debug_insn 52 51 53 9
/proj/opensrc/nightly/src/trunk/libgcc/../gcc/gcov-io.c:238 (var_location:SI
result (high (nil))) -1 (nil))

val is:

(plus:DI (const:DI (plus:DI (symbol_ref:DI ("__gcov_var") [flags 0x2] <var_decl
7b50cba0 __gcov_var>)
            (const_int 12 [0xc])))
    (mult:SI (plus:SI (reg:SI 340 [ prephitmp.26 ])
            (const_int 4 [0x4]))
        (const_int 4 [0x4])))

So the modes do not match.  I am compiling in 32 bit mode, so ptr_mode is
SImode but Pmode is DImode.

The original file was libgcov.c, I used delta to cut it down into an example
that will fail to compile with '-g -O2'.

Testcase:


struct __gcov_var {
   unsigned int offset;
   unsigned int buffer[(1 << 10) + 1];
} __gcov_var;
unsigned int * gcov_write_words (unsigned int words) {
   unsigned int *result;
   result = &__gcov_var.buffer[__gcov_var.offset];
   return result;
}

This patch, combined with Michael Matz's patch for PR41268, gave me a good
bootstrap on ia64-hp-hpux11.23,
