GCC modified for the FreeChainXenon project
5e6903ddd3
Verify, for generic integer conditional-add operations, if-conversion to trigger via `noce_try_addcc' at the respective sufficiently high `-mbranch-cost=' settings that make branchless code sequences produced by if-conversion cheaper than their original branched equivalents, and, where applicable, that extraneous instructions such as SNEZ, etc. are not present in output. Cover all integer relational operations to make sure no corner case escapes. The reason to XFAIL SImode tests for RV64 targets is the compiler thinks it has to sign-extend addends, which causes if-conversion to give up. gcc/testsuite/ * gcc.target/riscv/adddieq.c: New test. * gcc.target/riscv/adddige.c: New test. * gcc.target/riscv/adddigeu.c: New test. * gcc.target/riscv/adddigt.c: New test. * gcc.target/riscv/adddigtu.c: New test. * gcc.target/riscv/adddile.c: New test. * gcc.target/riscv/adddileu.c: New test. * gcc.target/riscv/adddilt.c: New test. * gcc.target/riscv/adddiltu.c: New test. * gcc.target/riscv/adddine.c: New test. * gcc.target/riscv/addsieq.c: New test. * gcc.target/riscv/addsige.c: New test. * gcc.target/riscv/addsigeu.c: New test. * gcc.target/riscv/addsigt.c: New test. * gcc.target/riscv/addsigtu.c: New test. * gcc.target/riscv/addsile.c: New test. * gcc.target/riscv/addsileu.c: New test. * gcc.target/riscv/addsilt.c: New test. * gcc.target/riscv/addsiltu.c: New test. * gcc.target/riscv/addsine.c: New test. |

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.
