parse_expr()

expr2tc clang_c_lexert::parse_expr

(

const std::string &

expr

)

Parse a C scalar-expression string into an IRep2 expression tree.

Uses the Clang raw lexer and NumericLiteralParser. Supports comparison operators (==, !=, <, <=, >, >=) composed with && and || and parenthesised sub-expressions.

The special token

Returns

is emitted as symbol2tc(int64, "\\result"). Integer constants are emitted as constant_int2tc(int64, N). Callers are responsible for retyping these nodes to the target type before use.

Parameters

expr	The expression string to parse.

Returns

The parsed IRep2 expression, or a null expr2tc on parse error.
