This is a "short" field getting a 32-bit-long constant. The gcc-14 error, above, tells me it's truncating to 0. For the time being, I'm just making that truncation explicit. (See? I told you not to merge this patch.)

Similarly, immed is long long (i.e. at least 64 bits), and parse_reg expects a pointer to a 32-bit quantity. Assuming we're on a little-endian system, it's a bad-but-seemingly-functional idea to cast between them like this. On a big-endian system it would certainly not work as expected.

FWIW Bumped into the same build errors on Debian 13, these patches fix the build issues. Can these be reworked towards a version that is mergeable? |

The binutils patches carried in meta-xilinx/meta-microblaze/recipes-devtools/binutils do not build when using gcc-14. This patch series contains two kinds of things:
Item (1) needs review, but item (2) needs some care and attention. This PR is not meant to be merged wholesale.
The patches themselves contain build error messages in fairly excruciating detail.
