From 2976822627f44f301cb3a74e71b9a0127aecec71 Mon Sep 17 00:00:00 2001 From: kenner Date: Sat, 19 Feb 2000 01:27:00 +0000 Subject: * bitmap.c (bitmap_operation): Avoid using -1 for index since unsigned. * cppinit.c (new_pending_define): Add cast to avoid warning. * expmed.c (extract_bit_field): Likewise. * flow.c (enum reorder_skip_type): New type. (skip_insns_between_blcok): New it. Rework to avoid warning about possibly undefined variable. * function.c (assign_parms): Make thisparm_boundary unsigned. * genrecog.c (write_switch): Cast XWINT result to int. * lcm.c: Many static fcns and vars now #ifdef OPTIMIZE_MODE_SWITCHING. * mips-tfile.c (init_file): Make two versions of FDR intializer: one for MIPS and one for Alpha. (get_tag, copy_object): Add casts to avoid warnings. * optabs.c (init_one_libfunc): Cast NAME to (char *). * reload.c (find_reloads): Make TYPE enum reload_type. * sbitmap.c (dump_sbitmap): J is unsigned; don't use "1L". * unroll.c (unroll_loop): Initialize UNROLL_NUMBER. * varasm.c (compare_constant_1): Add cast to avoid warning. * config/alpha/alpha.c (alpha_emit_xfloating_libcall): Cast FUNC to (char *). (alpha_expand_unaligned_load, alpha_expand_unaligned_store): Cast switch operand of size to int. (alpha_expand_epilogue): Always initialize fp_offset and sa_reg. * config/alpha/alpha.h (INITIAL_ELIMINATION_OFFSET): Add abort in unhandled case. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@32060 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/bitmap.c | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) (limited to 'gcc/bitmap.c') diff --git a/gcc/bitmap.c b/gcc/bitmap.c index 6c6c9787026..99b5f5a4e0e 100644 --- a/gcc/bitmap.c +++ b/gcc/bitmap.c @@ -395,10 +395,12 @@ bitmap_operation (to, from1, from2, operation) bitmap from2; enum bitmap_bits operation; { +#define HIGHEST_INDEX (unsigned int) ~0 + bitmap_element *from1_ptr = from1->first; bitmap_element *from2_ptr = from2->first; - unsigned int indx1 = (from1_ptr) ? from1_ptr->indx : -1; - unsigned int indx2 = (from2_ptr) ? from2_ptr->indx : -1; + unsigned int indx1 = (from1_ptr) ? from1_ptr->indx : HIGHEST_INDEX; + unsigned int indx2 = (from2_ptr) ? from2_ptr->indx : HIGHEST_INDEX; bitmap_element *to_ptr = to->first; bitmap_element *from1_tmp; bitmap_element *from2_tmp; @@ -449,9 +451,9 @@ bitmap_operation (to, from1, from2, operation) from1_tmp = from1_ptr; from2_tmp = from2_ptr; from1_ptr = from1_ptr->next; - indx1 = (from1_ptr) ? from1_ptr->indx : -1; + indx1 = (from1_ptr) ? from1_ptr->indx : HIGHEST_INDEX; from2_ptr = from2_ptr->next; - indx2 = (from2_ptr) ? from2_ptr->indx : -1; + indx2 = (from2_ptr) ? from2_ptr->indx : HIGHEST_INDEX; } else if (indx1 < indx2) { @@ -459,7 +461,7 @@ bitmap_operation (to, from1, from2, operation) from1_tmp = from1_ptr; from2_tmp = &bitmap_zero; from1_ptr = from1_ptr->next; - indx1 = (from1_ptr) ? from1_ptr->indx : -1; + indx1 = (from1_ptr) ? from1_ptr->indx : HIGHEST_INDEX; } else { @@ -467,7 +469,7 @@ bitmap_operation (to, from1, from2, operation) from1_tmp = &bitmap_zero; from2_tmp = from2_ptr; from2_ptr = from2_ptr->next; - indx2 = (from2_ptr) ? from2_ptr->indx : -1; + indx2 = (from2_ptr) ? from2_ptr->indx : HIGHEST_INDEX; } /* Find the appropriate element from TO.
