From 2eb833534c7e715c276658ecb810715e8718e5c3 Mon Sep 17 00:00:00 2001 From: "Jose E. Marchesi" Date: Wed, 22 Nov 2023 15:32:17 +0100 Subject: [PATCH] libgcc: mark __hardcfr_check_fail as always_inline The function __hardcfr_check_fail in hardcfr.c is internal and static inline. It receives many arguments, which require more than five registers to be passed in bpf-none-unknown targets. BPF is limited to that number of registers to pass arguments, and therefore libgcc fails to build in that target. This patch marks the function with the always_inline attribute, fixing the bpf build. Tested in bpf-unknown-none target and x86_64-linux-gnu host. libgcc/ChangeLog: * hardcfr.c (__hardcfr_check_fail): Mark as always_inline. --- libgcc/hardcfr.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/libgcc/hardcfr.c b/libgcc/hardcfr.c index 25ff06742cb4..376a36202c84 100644 --- a/libgcc/hardcfr.c +++ b/libgcc/hardcfr.c @@ -206,6 +206,10 @@ __hardcfr_debug_cfg (size_t const blocks, enabled, it also forces __hardcfr_debug_cfg (above) to be compiled into an out-of-line function, that could be called from a debugger. */ + +#ifdef __BPF__ +__attribute__((__always_inline__)) +#endif static inline void __hardcfr_check_fail (size_t const blocks ATTRIBUTE_UNUSED, vword const *const visited ATTRIBUTE_UNUSED, -- 2.47.2
