RS6000/PowerPC -mpaired

2016-01-05 Thread Alan Lawrence
Can anyone give me any pointers on how to use the -mpaired option ("PowerPC 
750CL paired-single instructions") ? I'm trying to get it to use the 
reduc_s{min,max,plus}_v2sf patterns in gcc/config/rs6000/paired.md, so far I 
haven't managed to find a configuration that supports loading a vector of floats 
but that doesn't also have superior altivec/v4sf support...


Thanks, Alan

Dear GCC Development Team,

I'm Ngoc, I'm an software engineer in Software Department at ICDREC
(www.icdrec.edu.vn)
Our work are build the tool-chains to support for microcontroller. Ex:
IDE, compiler,

Now, I'm planning to make a GCC port for a new 8 bits microcontroller.
And I want to
add it into official GCC source. But the normal account not have the
privilege to add a new target through git.

Can you tell me how to do this?

How can I become a maintainer to maintain ours if the code are approved?
