Error description
When compiling an application that uses the __d128_test_significance compiler built-in, and contains inline assembly code, the compile fails at the assemble step with the following error message: Assembler: filename.s: line 79: 1252-205 This instruction form requires the RS or RT register to be even. 1500-067:(S) asm statement generates errors in assembler output.
Local fix
- Remove inline ASM - Lower optimization level
Problem summary
PROBLEM DESCRIPTION: The compiler is generating incorrect forms for certain 128-bit DFP instructions. USERS AFFECTED: Users who use 128-bit DFP variables in their code.
Problem conclusion
The issue was fixed by ensuring the correct number of registers for the instruction, and to ensure register allocation has the correct constraints for the registers.
Temporary fix
