Hardcode SImode as outmode for libcalls to clz, ctz, popcount, and parity. (init_optabs): Init clz_optab, ctz_optab, popcount_optab and parity_optab, and set up libfunc handlers. * libgcc2.c (__clzsi2, __clzdi2, __ctzsi2, __ctzdi2, __popcountsi2, __popcountdi2, __paritysi2 __paritydi2, __popcount_tab): New. * libgcc2.h: Declare them. * libgcc-std.ver (GCC_3.4): Add new functions from libgcc2.c. * genopinit.c (optabs): Add clz_optab, ctz_optab, popcount_optab and parity_optab. * builtin-types.def (BT_FN_INT_LONG, BT_FN_INT_LONGLONG): New. * builtins.def (BUILT_IN_CLZ, BUILT_IN_CTZ, BUILT_IN_POPCOUNT, BUILT_IN_PARITY, BUILT_IN_FFSL, BUILT_IN_CLZL, BUILT_IN_CTZL, BUILT_IN_POPCOUNTL, BUILT_IN_PARITYL, BUILT_IN_FFSLL, BUILT_IN_CLZLL, BUILT_IN_CTZLL, BUILT_IN_POPCOUNTLL, BUILT_IN_PARITYLL): New. * builtins.c (expand_builtin_unop): Rename from expand_builtin_ffs and add optab argument. (expand_builtin): Expand BUILT_IN_{FFS,CLZ,POPCOUNT,PARITY}*. * tree.def (CLZ_EXPR, CTZ_EXPR, POPCOUNT_EXPR, PARITY_EXPR): New. * expr.c (expand_expr): Handle them. * fold-const.c (tree_expr_nonnegative_p): Likewise. * rtl.def (CLZ, CTZ, POPCOUNT, PARITY): New. * reload1.c (eliminate_regs): Handle them. (elimination_effects): Likewise. * function.c (instantiate_virtual_regs_1): Likewise * genattrtab.c (check_attr_value): Likewise. * simplify-rtx.c (simplify_unary_operation): Likewise. * c-common.c (c_common_truthvalue_conversion): Handle POPCOUNT_EXPR. * combine.c (combine_simplify_rtx): Handle POPCOUNT and PARITY. (nonzero_bits): Handle CLZ, CTZ, POPCOUNT and PARITY. * config/alpha/alpha.md (clzdi2, ctzdi2, popcountdi2): New. * config/arm/arm.c (arm_init_builtins): Rename __builtin_clz to __builtin_arm_clz. * Makefile.in (LIB2FUNCS_1, LIB2FUNCS_2): Move... * mklibgcc.in (lib2funcs): ...here and merge. Add new members. * doc/extend.texi (Other Builtins): Add new builtins. * doc/md.texi (Standard Names): Add new patterns. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@62252 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/reload1.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'gcc/reload1.c') diff --git a/gcc/reload1.c b/gcc/reload1.c index 90625dbee67..f6498f10e29 100644 --- a/gcc/reload1.c +++ b/gcc/reload1.c @@ -2545,6 +2545,10 @@ eliminate_regs (x, mem_mode, insn) case ABS: case SQRT: case FFS: + case CLZ: + case CTZ: + case POPCOUNT: + case PARITY: new = eliminate_regs (XEXP (x, 0), mem_mode, insn); if (new != XEXP (x, 0)) return gen_rtx_fmt_e (code, GET_MODE (x), new); @@ -2776,6 +2780,10 @@ elimination_effects (x, mem_mode) case ABS: case SQRT: case FFS: + case CLZ: + case CTZ: + case POPCOUNT: + case PARITY: elimination_effects (XEXP (x, 0), mem_mode); return; -- cgit v1.2.1
