            Bug ID: 29163
           Summary: [gdb/m2] parse_number needs rewrite
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: m2
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

When building with -fsanitize=undefined, I run into:
...
$ gdb -q -batch -ex "set lang modula-2" -ex "p /x 010000000000000000H"
/home/vries/gdb_versions/devel/src/gdb/m2-exp.y:627:9: runtime error: signed
integer overflow: 1152921504606846976 * 16 cannot be represented in type 'long
int'
$1 = 0x0
...

I guess the parser needs to be rewritten to use ULONGEST, like all the others.

Note that the parser is different from others in that it uses the number_sign
indicator, so we'll have to add negative number cases as well to
gdb.base/parse_number.exp.

Likewise, different line:
...
$ gdb -q -batch -ex "set lang modula-2" -ex "p /x -9223372036854775808"
/home/vries/gdb_versions/devel/src/gdb/m2-exp.y:639:8: runtime error: signed
integer overflow: 9223372036854775800 + 8 cannot be represented in type 'long
int'
Overflow on numeric constant.
