Assert that a floating type's length is at least as long as its format
This would have caught the HP/PA bug fixed in the previous patch:
.../src/gdb/gdbtypes.c:4690: internal-error: arch_float_type: Assertion `len >= floatformat_totalsize_bytes (floatformats[0])' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
Tested on x86-64 Fedora 23, --enable-targets=all.
gdb/ChangeLog:
2016-03-09 Pedro Alves <palves@redhat.com>
* doublest.c (floatformat_totalsize_bytes): New function.
(floatformat_from_type): Assert that the type's length is at least
as long as the floatformat's totalsize.
* doublest.h (floatformat_totalsize_bytes): New declaration.
* gdbtypes.c (arch_float_type): Assert that the type's length is
at least as long as the floatformat's totalsize.
