Hello, I am working on a gcc porting for a new instruction. This
instruction needs to move data from memory to two registers. So I use
the SET rtx, and the dest of SET is an UNSPEC rtx with two registers.
By using such a rtl pattern, gcc performs very differently. It makes
mistakes for register rep
Hello,
After I compile the following file for testing, I check the dump
file called "129t.final_cleanup". I doubt about why the type "short
int" changes into "short unsigned int" during the array operations,
and at last changes back to "short int" when it stores the result into
memory.

Hello,
After I vectorize the following file by GCC for testing, it gets the

vector type when stores the "short int" into memory. I have checked

The source file is:
short i
