Bug ID: 18189
Summary: Extra-large constant handling failure in microblaze
Product: binutils
Version: 2.25
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org

libgcc derived assembly file that shows the problem.
Attempting to assemble this line with a microblaze-linux-gnu target assembler:
addik r23,r0,0xb746a0003f800000
works when the compiler is x86_64 hosted but fails when i386 hosted with the
following error:
_powisf2.s: Assembler messages:
_powisf2.s:71: Fatal error: operand must be a constant or a label
Given that microblaze is 32-bit only, I would guess that the error should
appear on x86_64 as well as on i386 - and that this is actually a symptom of a
gcc bug.
The error can be obtained by running the attached assembly file through the
assembler thusly:
microblaze-linux-gnu-as _powisf2.s
