From f7a858bffcddaaf70c71b6b656e7cc21b6107cec Mon Sep 17 00:00:00 2001 From: Liam Howlett Date: Fri, 25 Nov 2022 15:50:16 +0000 Subject: tools: Rename __fallthrough to fallthrough MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rename the fallthrough attribute to better align with the kernel version. Copy the definition from include/linux/compiler_attributes.h including the #else clause. Adding the #else clause allows the tools compiler.h header to drop the check for a definition entirely and keeps both definitions together. Change any __fallthrough statements to fallthrough anywhere it was used within perf. This allows other tools to use the same key word as the kernel. Committer notes: Did some missing conversions to: builtin-list.c Also included gtk.h before the 'fallthrough' definition in: tools/perf/ui/gtk/hists.c tools/perf/ui/gtk/helpline.c tools/perf/ui/gtk/browser.c As it is the arg name for a macro in glib.h: /var/home/acme/git/perf-tools-next/tools/include/linux/compiler-gcc.h:16:55: error: missing binary operator before token "(" 16 | # define fallthrough __attribute__((__fallthrough__)) | ^ /usr/include/glib-2.0/glib/gmacros.h:637:28: note: in expansion of macro ‘fallthrough’ 637 | #if g_macro__has_attribute(fallthrough) Reviewed-by: Miguel Ojeda Signed-off-by: Liam Howlett Cc: Ingo Molnar Cc: Mark Rutland Cc: Miguel Ojeda Cc: Nathan Chancellor Cc: Nick Desaulniers Cc: Peter Zijlstra Cc: Rasmus Villemoes Cc: Tom Rix Cc: linux-sparse@vger.kernel.org Cc: llvm@lists.linux.dev Link: https://lore.kernel.org/r/20221125154947.2163498-1-Liam.Howlett@oracle.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/callchain.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'tools/perf/util/callchain.c') diff --git a/tools/perf/util/callchain.c b/tools/perf/util/callchain.c index 9e9c39dd9d2b..8e7c29836765 100644 --- a/tools/perf/util/callchain.c +++ b/tools/perf/util/callchain.c @@ -724,7 +724,7 @@ static enum match_result match_chain(struct callchain_cursor_node *node, if (match != MATCH_ERROR) break; /* otherwise fall-back to symbol-based comparison below */ - __fallthrough; + fallthrough; case CCKEY_FUNCTION: if (node->ms.sym && cnode->ms.sym) { /* @@ -745,7 +745,7 @@ static enum match_result match_chain(struct callchain_cursor_node *node, } } /* otherwise fall-back to IP-based comparison below */ - __fallthrough; + fallthrough; case CCKEY_ADDRESS: default: match = match_chain_dso_addresses(cnode->ms.map, cnode->ip, node->ms.map, node->ip); -- cgit
