NAME

6       arch_has_block_step - does this CPU support user-mode block-step?

SYNOPSIS

9       arch_has_block_step(void);

ARGUMENTS

12       None

DESCRIPTION

15       If this is defined, then there must be a function declaration or inline
16       for user_enable_block_step, and arch_has_single_step must be defined
17       too.  arch_has_block_step should evaluate to nonzero iff the machine
18       supports step-until-branch for user mode. It can be a constant or it
19       can test a CPU feature bit.
