| Subject: [PATCH] Fix internal compiler error with msmall-divides |
| |
| This patch will fix the internal error microblaze_expand_divide function |
| which comes because of rtx PLUS where the mem_rtx is of type SI and the |
| operand is of type QImode. This patch modifies the mem_rtx as QImode and |
| Plus as QImode to fix the error. |
