This patch adds that information to the description of `-Ofast` in `FlangDriver.md`. --- flang/docs/FlangDriver.md | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/flang/docs/FlangDriver.md b/flang/docs/FlangDriver.md index 9953f2252218b..63f2ce3e67570 100644 --- a/flang/docs/FlangDriver.md +++ b/flang/docs/FlangDriver.md @@ -559,7 +559,7 @@ See the documentation for more details. ## Ofast and Fast Math -`-Ofast` in Flang means `-O3 -ffast-math -fstack-arrays`. +`-Ofast` in Flang means `-O3 -ffast-math -fstack-arrays -fno-protect-parens`. `-ffast-math` means the following: - `-fno-honor-infinities` >From 4b8a33f99f7000b5155cb5dbca605121386d2131 Mon Sep 17 00:00:00 2001 From: s-watanabe314 <[email protected]> Date: Tue, 10 Feb 2026 09:44:55 +0900 Subject: [PATCH 2/2] Update the help text --- clang/include/clang/Options/Options.td | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/clang/include/clang/Options/Options.td b/clang/include/clang/Options/Options.td index 5ecb516c2cf68..21c126950c5e0 100644 --- a/clang/include/clang/Options/Options.td +++ b/clang/include/clang/Options/Options.td @@ -849,7 +849,7 @@ def O_flag : Flag<["-"], "O">, Visibility<[ClangOption, CC1Option, FC1Option]>, def Ofast : Joined<["-"], "Ofast">, Group<O_Group>, Visibility<[ClangOption, CC1Option, FlangOption, FC1Option]>, HelpTextForVariants<[FlangOption, FC1Option], - "Deprecated; use '-O3 -ffast-math -fstack-arrays' for the same behavior," + "Deprecated; use '-O3 -ffast-math -fstack-arrays -fno-protect-parens' for the same behavior," " or '-O3 -fstack-arrays' to enable only conforming optimizations">, HelpText<"Deprecated; use '-O3 -ffast-math' for the same behavior," " or '-O3' to enable only conforming optimizations">; _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
