armv8-m.base (cortex-m23) has the movt instruction, so we need to disable the define_split to generate a constant in this case, otherwise we get incorrect insn constraints as described in PR94538. We also need to fix the pure-code alternative for thumb1_movsi_insn because the assembler complains with instructions like movs r0, #:upper8_15:1234 (Internal error in md_apply_fix) We now generate movs r0, 4 instead. 2020-08-24 Christophe Lyon <christophe.lyon@linaro.org> PR target/94538 gcc/ * config/arm/thumb1.md: Disable set-constant splitter when TARGET_HAVE_MOVT.

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.
