From ca3867d783d610d1990a137d6a9387168dda6605 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?John=20H=C3=B6gberg?= Date: Thu, 26 Jul 2018 14:35:25 +0200 Subject: Omit include path debug info for +deterministic builds Compiling the same file with different include paths resulted in different files with the `+deterministic` flag even if everything but the paths were identical. This was caused by the absolute path of each include directory being unconditionally included in a debug information chunk. This commit fixes this by only including this information in non-deterministic builds. --- lib/compiler/src/compile.erl | 29 ++++++++++++++++++++++------- 1 file changed, 22 insertions(+), 7 deletions(-) (limited to 'lib/compiler/src/compile.erl') diff --git a/lib/compiler/src/compile.erl b/lib/compiler/src/compile.erl index 50b0ba76f8..4203d79913 100644 --- a/lib/compiler/src/compile.erl +++ b/lib/compiler/src/compile.erl @@ -1408,16 +1408,30 @@ encrypt_debug_info(DebugInfo, Key, Opts) -> end. cleanup_compile_options(Opts) -> - lists:filter(fun keep_compile_option/1, Opts). - + IsDeterministic = lists:member(deterministic, Opts), + lists:filter(fun(Opt) -> + keep_compile_option(Opt, IsDeterministic) + end, Opts). + +%% Include paths and current directory don't affect compilation, but they might +%% be helpful so we include them unless we're doing a deterministic build. +keep_compile_option({i, _}, Deterministic) -> + not Deterministic; +keep_compile_option({cwd, _}, Deterministic) -> + not Deterministic; %% We are storing abstract, not asm or core. -keep_compile_option(from_asm) -> false; -keep_compile_option(from_core) -> false; +keep_compile_option(from_asm, _Deterministic) -> + false; +keep_compile_option(from_core, _Deterministic) -> + false; %% Parse transform and macros have already been applied. -keep_compile_option({parse_transform, _}) -> false; -keep_compile_option({d, _, _}) -> false; +keep_compile_option({parse_transform, _}, _Deterministic) -> + false; +keep_compile_option({d, _, _}, _Deterministic) -> + false; %% Do not affect compilation result on future calls. -keep_compile_option(Option) -> effects_code_generation(Option). +keep_compile_option(Option, _Deterministic) -> + effects_code_generation(Option). start_crypto() -> try crypto:start() of @@ -1548,6 +1562,7 @@ effects_code_generation(Option) -> binary -> false; verbose -> false; {cwd,_} -> false; + {i,_} -> false; {outdir, _} -> false; _ -> true end. -- cgit v1.2.3
