| | | | | | | | | | | | | | | | | | * cse.c (table_size): New static variable. (new_basic_block): Initialize it to 0. (remove_from_table): Decrement it. (insert): Increment it. (fold_rtx_mem_1): New function, renamed from fold_rtx_mem. (fold_rtx_mem): Enforce a cap on the recursion depth. Call fold_rtx_mem_1 if under the cap. (fold_rtx) <RTX_COMM_ARITH>: In the associative case, delay a little the lookup of the equivalent expression and test for equality of the first operand of the equivalent expression before in turn looking up an equivalent constant for the second operand. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@116683 138bc75d-0d04-0410-961f-82ee72b054a4

| | | | | | | | | | | | | | | * cse.c (fold_rtx): Correctly associate shifts when const_arg1 and/or inner_const are negative or greater than or equal to the bitsize of MODE. If SHIFT_COUNT_TRUNCATED is false, the values aren't associated. Otherwise, the values are masked using GET_MODE_BITSIZE (mode) - 1. Simplify complicated if statement. For ASHIFT and LSHIFTRT, return CONST0_RTX (mode) when the new shift count is greater than or equal to to the bitsize of the object being shifted and XEXP (y, 0) has no side effects. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@115924 138bc75d-0d04-0410-961f-82ee72b054a4
