From dc4e9384c6f2f733ab0d12727ab53238bda3fbca Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Magnus=20L=C3=A5ng?= Date: Thu, 17 Mar 2016 21:37:26 +0100 Subject: hipe_x86: Minimise CFG<->linear conversions Most x86 passes were either linearise(pass(to_cfg(Code))) or trivially rewritable to process a CFG. This saves a great deal of time and memory churn when compiling large programs. Now, there will only ever be a single Linear->CFG conversion, just after lowering from RTL, and only ever a single CFG->Linear conversion, just before the finalise pass. Both of these now happen in hipe_x86_main. --- .../amd64/hipe_amd64_ra_sse2_postconditions.erl | 107 ++++++--------------- lib/hipe/amd64/hipe_amd64_sse2.erl | 9 +- lib/hipe/flow/cfg.inc | 50 +++++++++- lib/hipe/flow/hipe_bb.erl | 2 + lib/hipe/regalloc/hipe_amd64_specific_sse2.erl | 12 +-- lib/hipe/regalloc/hipe_x86_specific.erl | 8 +- lib/hipe/regalloc/hipe_x86_specific_x87.erl | 4 +- lib/hipe/x86/hipe_x86_cfg.erl | 5 +- lib/hipe/x86/hipe_x86_frame.erl | 56 ++++------- lib/hipe/x86/hipe_x86_main.erl | 22 +++-- lib/hipe/x86/hipe_x86_ra.erl | 64 ++++++------ lib/hipe/x86/hipe_x86_ra_finalise.erl | 25 ++--- lib/hipe/x86/hipe_x86_ra_ls.erl | 32 +++--- lib/hipe/x86/hipe_x86_ra_naive.erl | 11 ++- lib/hipe/x86/hipe_x86_ra_postconditions.erl | 14 ++- lib/hipe/x86/hipe_x86_spill_restore.erl | 12 +-- lib/hipe/x86/hipe_x86_x87.erl | 5 +- 17 files changed, 216 insertions(+), 222 deletions(-) (limited to 'lib') diff --git a/lib/hipe/amd64/hipe_amd64_ra_sse2_postconditions.erl b/lib/hipe/amd64/hipe_amd64_ra_sse2_postconditions.erl index 8483d2d0d5..bbf9170bc3 100644 --- a/lib/hipe/amd64/hipe_amd64_ra_sse2_postconditions.erl +++ b/lib/hipe/amd64/hipe_amd64_ra_sse2_postconditions.erl @@ -29,17 +29,21 @@ -define(count_temp(T), ?cons_counter(counter_mfa_mem_temps, T)). -check_and_rewrite(AMD64Defun, Coloring) -> - check_and_rewrite(AMD64Defun, Coloring, 'normal'). +check_and_rewrite(AMD64CFG, Coloring) -> + check_and_rewrite(AMD64CFG, Coloring, 'normal'). -check_and_rewrite(AMD64Defun, Coloring, Strategy) -> +check_and_rewrite(AMD64CFG, Coloring, Strategy) -> %%io:format("Converting\n"), TempMap = hipe_temp_map:cols2tuple(Coloring,hipe_amd64_specific_sse2), %%io:format("Rewriting\n"), - #defun{code=Code0} = AMD64Defun, - {Code1, DidSpill} = do_insns(Code0, TempMap, Strategy, [], false), - {AMD64Defun#defun{code=Code1, var_range={0, hipe_gensym:get_var(x86)}}, - DidSpill}. + do_bbs(hipe_x86_cfg:labels(AMD64CFG), TempMap, Strategy, AMD64CFG, false). + +do_bbs([], _, _, CFG, DidSpill) -> {CFG, DidSpill};
