EQ R0, R1;
WHEREEQ
vector_asm_instr1;
...
vector_asm_instrk;
ENDWHERE
I was able to generate at instruction selection such a block by writing custom C++
selection code, but I don't know how can I inform the back end that the instructions
inside the WHERE block get executed conditionally, not always.
This matters it seems only for o...
