GCC modified for the FreeChainXenon project
152d945d42
This commit makes the BPF backend to define the following macros for
c-family languages:
__BPF_CPU_VERSION__
This is a numeric value identifying the version of the BPF "cpu"
for which GCC is generating code.
__BPF_FEATURE_ALU32
__BPF_FEATURE_JMP32
__BPF_FEATURE_JMP_EXT
__BPF_FEATURE_BSWAP
__BPF_FEATURE_SDIV_SMOD
__BPF_FEATURE_MOVSX
__BPF_FEATURE_LDSX
__BPF_FEATURE_GOTOL
__BPF_FEATURE_ST
These are defines if the corresponding "feature" is enabled. The
features are implicitly enabled by the BPF CPU version enabled,
and most of them can also be enabled/disabled using
target-specific -m[no-]FEATURE command line switches.
Note that this patch moves the definition of bpf_target_macros, that
implements TARGET_CPU_CPP_BUILTINS in the BPF backend, to a bpf-c.cc
file. This is because we are now using facilities from c-family/* and
these features are not available in compilers like lto1.
A couple of tests are also added.
Tested in target bpf-unknown-none-gcc and host x86_64-linux-gnu.
No regressions.

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.
