From 56579f8ade21cb0a880ffbd6d5e28f152e951be8 Mon Sep 17 00:00:00 2001 From: xleroy Date: Sun, 6 Apr 2014 07:11:12 +0000 Subject: Merge of branch linear-typing: 1) Revised division of labor between RTLtyping and Lineartyping: - RTLtyping no longer keeps track of single-precision floats, switches from subtype-based inference to unification-based inference. - Unityping: new library for unification-based inference. - Locations: don't normalize at assignment in a stack slot - Allocation, Allocproof: simplify accordingly. - Lineartyping: add inference of locations that contain a single-precision float. - Stackingproof: adapted accordingly. This addresses a defect report whereas RTLtyping was rejecting code that used a RTL pseudoreg to hold both double- and single-precision floats (see test/regression/singlefloats.c). This corresponds to commits 2435+2436 plus improvements in Lineartyping. 2) Add -dtimings option to measure compilation times. Moved call to C parser from Elab to Parse, to make it easier to measure parsing time independently of elaboration time. git-svn-id: https://yquem.inria.fr/compcert/svn/compcert/trunk@2449 fca1b0fc-160b-0410-b1d3-a4f43f01ea2e --- driver/Driver.ml | 2 ++ 1 file changed, 2 insertions(+) (limited to 'driver/Driver.ml') diff --git a/driver/Driver.ml b/driver/Driver.ml index 8853794..e768fa2 100644 --- a/driver/Driver.ml +++ b/driver/Driver.ml @@ -457,6 +457,7 @@ Tracing options: General options: -stdlib Set the path of the Compcert run-time library -v Print external commands before invoking them + -timings Show the time spent in various compiler passes Interpreter mode: -interp Execute given .c files using the reference interpreter -quiet Suppress diagnostic messages for the interpreter @@ -529,6 +530,7 @@ let cmdline_actions = push_linker_arg s); "-Os$", Set option_Osize; "-O$", Unset option_Osize; + "-timings$", Set option_timings; "-fsmall-data$", Integer(fun n -> option_small_data := n); "-fsmall-const$", Integer(fun n -> option_small_const := n); "-ffloat-const-prop$", Integer(fun n -> option_ffloatconstprop := n); -- cgit v1.2.3
