eclass/flag-o-matic.eclass: Add missing MIPS CPU errata flags |
| 9 |
|
| 10 |
Noticed during a glibc build for MIPS-III ISA that the -mfix-r4000 |
| 11 |
and -mfix-r4400 gcc flags got stripped off. These are needed to work |
| 12 |
around known CPU errata in R4000 and R4400 CPUs. In addition, also |
| 13 |
add the -mfix-rm7000 option (and it's -mno form) to fix errata in the |
| 14 |
PMC RM7000 CPU, and the -mr10k-cache-barrier to control the generation |
| 15 |
of cache barriers to work around the side-effects of R10000's |
| 16 |
speculative execution capabilities. |
