- Subject: [PATCH]: cleanup for conversion exprs code patterns (11/16)
Hi,
this series of patches is doing small cleanup in using conversion
expressions code patterns. There is a lot of duplicate code patterns
for conversion expressions (CONVERT_EXPR, NOP_EXPR, NON_LVALUE_EXPR)
that can be substituted by macro. Patterns are:
(TREE_CODE (EXP) == NOP_EXPR || TREE_CODE (EXP) == CONVERT_EXPR)
-> TEST_CONVERT_NOPS_P(EXP)
(TREE_CODE (EXP) == NOP_EXPR || TREE_CODE (EXP) == CONVERT_EXPR
|| TREE_CODE (EXP) == NON_LVALUE_EXPR)
-> TEST_NOPS_P(EXP)
case NOP_EXPR: case CONVERT_EXPR
-> CASE_CONVERT_NOPS
case NOP_EXPR: case CONVERT_EXPR: case NON_LVALUE_EXPR
-> CASE_NOPS
while (TREE_CODE (EXP) == NOP_EXPR
|| TREE_CODE (EXP) == CONVERT_EXPR
|| TREE_CODE (EXP) == NON_LVALUE_EXPR)
(EXP) = TREE_OPERAND (EXP, 0)
-> STRIP_NOPS_UNSAFE(EXP)
-> means replaced by
Patch 1: Add new macros (TEST_CONVERT_NOPS_P(EXP), TEST_NOPS_P(EXP),
CASE_CONVERT_NOPS, CASE_NOPS, STRIP_NOPS_UNSAFE(EXP)).
Patch 2-4: Add support of TEST_CONVERT_NOPS_P.
Patch 5-8: Add support of TEST_NOPS_P.
Patch 9-11: Add support of CASE_CONVERT_NOPS.
Patch 12-13: Add support of CASE_NOPS.
Patch 14-16: Add support of STRIP_NOPS_UNSAFE.
Bootstraped and tested on x86_64 x86_64 GNU/Linux.
Ok?
Greetings
Tomas
