* trans-stmt.c (generate_loop_for_temp_to_lhs): Add an additional INVERT argument to invert the sense of the WHEREMASK argument. Remove unneeded code to AND together a list of masks. (generate_loop_for_rhs_to_temp): Likewise. (gfc_trans_assign_need_temp): Likewise. (gfc_trans_forall_1): Likewise. (gfc_evaluate_where_mask): Likewise, add a new INVERT argument to specify the sense of the MASK argument. (gfc_trans_where_assign): Likewise. (gfc_trans_where_2): Likewise. Restructure code that decides whether we need to allocate zero, one or two temporary masks. If this is a top-level WHERE (i.e. the incoming MAKS is NULL), we only need to allocate at most one temporary mask, and can invert it's sense to provide the complementary pending execution mask. Only calculate the size of the required temporary arrays if we need any. (gfc_trans_where): Update call to gfc_trans_where_2. From-SVN: r111630
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*.
