/* ??? Linux kernels provide an AUXV entry AT_HWCAP that provides most of
|
|
||||||
this information. However, getting at that entry is not easy this far
|
|
||||||
away from main. Our options are: start searching from environ, but
|
|
||||||
that fails as soon as someone does a setenv in between. Read the data
|
|
||||||
from /proc/self/auxv. Or do the probing ourselves. The only thing
|
|
||||||
extra that AT_HWCAP gives us is HWCAP_S390_HIGH_GPRS, which indicates
|
|
||||||
that the kernel saves all 64-bits of the registers around traps while
|
|
||||||
in 31-bit mode. But this is true of all "recent" kernels (ought to dig
|
|
||||||
back and see from when this might not be true). */
