From f8cc6a191723d763fc7a8908f3e5beb4eff8317f Mon Sep 17 00:00:00 2001 From: Andrew Kelley Date: Thu, 2 Apr 2020 21:15:36 -0400 Subject: [PATCH 1/3] zig cc: fix ambiguity with -MT In an MSVC context, `-MT` means "Use static run-time" and it is a flag with no parameter. On POSIX it means "Specify name of main file output in depfile" and it is "joined or separate". The former was interfering with the latter. Now, the MT flag is required to be specified with a `/` to disambiguate: `/MT`. --- src-self-hosted/clang_options.zig | 10 ++++ src-self-hosted/clang_options_data.zig | 74 ++++++++++++++++++++------ tools/update_clang_options.zig | 37 ++++++++++++- 3 files changed, 104 insertions(+), 17 deletions(-) diff --git a/src-self-hosted/clang_options.zig b/src-self-hosted/clang_options.zig index 70525655de..1b70c71dac 100644 --- a/src-self-hosted/clang_options.zig +++ b/src-self-hosted/clang_options.zig @@ -95,6 +95,16 @@ pub fn flagpd1(name: []const u8) CliArg { };
