Subject: [PATCH V5 09/11] bpf: adjust GCC testsuite to eBPF limitations
Date: Wed, 28 Aug 2019 23:47:53 +0200
Message-Id: <20190828214755.20951-10-jose.marchesi@oracle.com>
In-Reply-To: <20190828214755.20951-1-jose.marchesi@oracle.com>
References: <20190828214755.20951-1-jose.marchesi@oracle.com>
X-IsSubscribed: yes

This patch makes many tests in gcc.dg and gcc.c-torture to be skipped
in bpf-*-* targets.  This is due to the many limitations imposed by
eBPF to what would be perfectly valid C code: no support for more than
5 arguments to function calls, no support for indirect jumps, a very
limited range for direct jumps, etc.

Hopefully some of these restrictions will be relaxed in the future.
Also, as semantics associated with object linking get developed in
eBPF, it may be possible at some point to provide a set of standard
run-time libraries for eBPF programs.

gcc/testsuite/ChangeLog:

	* gcc.dg/builtins-config.h: eBPF doesn't support C99 standard
	functions.
	* gcc.c-torture/compile/20101217-1.c: Add a function prototype for
	printf.
