[PATCH v2 11/14] target/arm: default SVE length to 64 bytes for linux-user

2019-11-30 Thread Alex Bennée
The Linux kernel chooses the default of 64 bytes for SVE registers on the basis that it is the largest size that won't grow the signal frame. When debugging larger sizes are also unwieldy in gdb as each zreg will take over a page of terminal to display. The user can of course always specify a larg
