GCC generates the (target) machine code for every +compilation unit even with `-flto` (so it makes sense to distribute +these). And the whole program analysis is not guaranteed to be +the bottleneck of the build. As a matter of fact distributing +LTO compilations reduces the build time of LLVM/clang, GCC, and +other programs (especially C++ ones). + +Closes: #428 +--- + src/arg.c | 3 --- + 1 file changed, 3 deletions(-) + +diff --git a/src/arg.c b/src/arg.c +index 73ff707f..6ca5130e 100644 +--- a/src/arg.c ++++ b/src/arg.c +@@ -189,9 +189,6 @@ int dcc_scan_args(char *argv[], char **input_file, char **output_file, + rs_trace("-mtune=native optimizes for local machine; " + "must be local"); + return EXIT_DISTCC_FAILED; +- } else if (!strcmp(a, "-flto")) { +- rs_trace("LTO cc invocations are not worth distributing"); +- return EXIT_DISTCC_FAILED; + } else if (str_startswith("-Wa,", a)) { + /* Look for assembler options that would produce output + * files and must be local. -- cgit v1.2.3
