Hi Geng Qi,
I tested this patch but it got the following error when compiling libgcc,
during RTL pass:
reload/lhome/quxm/build-csky-upstream/source//gcc/libgcc/libgcc2.c: In
function
'__mulsc3':/lhome/quxm/build-csky-upstream/source//gcc/libgcc/libgcc2.c:2010:1:
internal compiler error: max
gcc/ChangeLog:
* config/csky/constraints.md ("W"): New constriant for mem operand
with base reg, index register.
("Q"): Renamed and modified "csky_valid_fpuv2_mem_operand" to
"csky_valid_mem_constraint_operand" to deal with both "Q" and "W"
constraint.
Hi Gengqi,
Is this patch based on the master branch? I cannot apply it successfully.
