Detailed Description

For GENERIC we have to take care of wrapping multiple-used
expressions with side-effects in save_expr and preserve side-effects
of expressions with omit_one_operand.  Analyze captures in
match, result and with expressions and perform early-outs
on the outermost match expression operands for cases we cannot

Constructor & Destructor Documentation

◆ capture_info()

capture_info::capture_info ( simplify * s,
operand * result,
bool gimple_ )

Member Function Documentation

◆ walk_c_expr()

void capture_info::walk_c_expr ( c_expr * e)

◆ walk_match()

void capture_info::walk_match ( operand * o,
unsigned toplevel_arg,
bool conditional_p,
bool cond_expr_cond_p )
Analyze captures in the match expression piece O.

◆ walk_result()

bool capture_info::walk_result ( operand * o,
bool conditional_p,
operand * result )
Analyze captures in the result expression piece O.  Return true
if RESULT was visited in one of the children.  Only visit
non-if/with children if they are rooted on RESULT.
