Here, if cp_perform_integral_promotions saw that the TREE_TYPE of a bit-field reference was the same as the type it promotes to, it didn't do anything. But then decay_conversion saw that the bit-field reference was unchanged, and converted it to its declared type. So I needed to add something to make it clear that promotion has been done. But then the 33819 change caused trouble by looking through the NOP_EXPR I just added. This was the wrong fix for that bug; I've now fixed that better by recognizing in cp_perform_integral_promotions that we won't promote a bit-field larger than 32 bits, so we should use the declared type. PR c++/33819 - long bit-field promotion. * typeck.c (cp_perform_integral_promotions): Handle large bit-fields properly. Handle 32-bit non-int bit-fields properly. (is_bitfield_expr_with_lowered_type): Don't look through NOP_EXPR. From-SVN: r275746 |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with 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*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
