GCC modified for the FreeChainXenon project
c96c2a304b
At this point the kernel headers that almost all BPF programs use contain pseudo-C inline assembly and having the GNU toolchain using the conventional assembly syntax by default would force users to specify the command-line option explicitly almost all of the time, which is very inconvenient. This patch changes GCC in order to recognize and generate the pseudo-C assembly syntax of BPF by default. The ASM_SPEC is adapted accordingly, and in a way that the current release of the BPF assembler (which still expects conventional assembler syntax by default) does the right thing. Tested in bpf-unknown-none-bpf target and x86_64-linux-gnu host. No regressions. gcc/ChangeLog * config/bpf/bpf.opt: Use ASM_PSEUDOC for the default value of -masm. * config/bpf/bpf.h (ASM_SPEC): Adapt accordingly. * doc/invoke.texi (eBPF Options): Update. gcc/testsuite/ChangeLog * gcc.target/bpf/alu-1.c: Specify conventional asm dialect. * gcc.target/bpf/xbpf-indirect-call-1.c: Likewise. * gcc.target/bpf/sync-fetch-and-add.c: Likewise. * gcc.target/bpf/smov-2.c: Likewise. * gcc.target/bpf/smov-1.c: Likewise. * gcc.target/bpf/smod-1.c: Likewise. * gcc.target/bpf/sload-1.c: Likewise. * gcc.target/bpf/sdiv-1.c: Likewise. * gcc.target/bpf/nop-1.c: Likewise. * gcc.target/bpf/neg-1.c: Likewise. * gcc.target/bpf/ldxdw.c: Likewise. * gcc.target/bpf/jmp-1.c: Likewise. * gcc.target/bpf/inline-memops-threshold-1.c: Likewise. * gcc.target/bpf/float-1.c: Likewise. * gcc.target/bpf/double-2.c: Likewise. * gcc.target/bpf/double-1.c: Likewise. * gcc.target/bpf/core-builtin-type-id.c: Likewise. * gcc.target/bpf/core-builtin-type-based.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-size-1.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-sign-2.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-sign-1.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-rshift-2.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-rshift-1.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-offset-1.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-lshift-2.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-lshift-1-le.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-lshift-1-be.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-existence-1.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-errors-2.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-errors-1.c: Likewise. * gcc.target/bpf/core-builtin-fieldinfo-const-elimination.c: Likewise. * gcc.target/bpf/core-builtin-exprlist-4.c: Likewise. * gcc.target/bpf/core-builtin-exprlist-3.c: Likewise. * gcc.target/bpf/core-builtin-exprlist-2.c: Likewise. * gcc.target/bpf/core-builtin-exprlist-1.c: Likewise. * gcc.target/bpf/core-builtin-enumvalue-opt.c: Likewise. * gcc.target/bpf/core-builtin-enumvalue-errors.c: Likewise. * gcc.target/bpf/core-builtin-enumvalue.c: Likewise. * gcc.target/bpf/core-builtin-3.c: Likewise. * gcc.target/bpf/core-builtin-2.c: Likewise. * gcc.target/bpf/core-builtin-1.c: Likewise. * gcc.target/bpf/core-attr-struct-as-array.c: Likewise. * gcc.target/bpf/core-attr-6.c: Likewise. * gcc.target/bpf/core-attr-5.c: Likewise. * gcc.target/bpf/core-attr-4.c: Likewise. * gcc.target/bpf/core-attr-3.c: Likewise. * gcc.target/bpf/core-attr-2.c: Likewise. * gcc.target/bpf/core-attr-1.c: Likewise. * gcc.target/bpf/builtin-load.c: Likewise. * gcc.target/bpf/btfext-funcinfo-nocore.c: Likewise. * gcc.target/bpf/btfext-funcinfo.c: Likewise. * gcc.target/bpf/bswap-1.c: Likewise. * gcc.target/bpf/bswap-2.c: Likewise. * gcc.target/bpf/attr-kernel-helper.c: Likewise. * gcc.target/bpf/atomic-xchg-2.c: Likewise. * gcc.target/bpf/atomic-xchg-1.c: Likewise. * gcc.target/bpf/atomic-op-3.c: Likewise. * gcc.target/bpf/atomic-op-2.c: Likewise. * gcc.target/bpf/atomic-op-1.c: Likewise. * gcc.target/bpf/atomic-fetch-op-3.c: Likewise. * gcc.target/bpf/atomic-fetch-op-2.c: Likewise. * gcc.target/bpf/atomic-fetch-op-1.c: Likewise. * gcc.target/bpf/atomic-cmpxchg-2.c: Likewise. * gcc.target/bpf/atomic-cmpxchg-1.c: Likewise. * gcc.target/bpf/alu-2.c: Likewise. |

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.
