From 29c2de1044d25c5ae641797e527ca72df8495355 Mon Sep 17 00:00:00 2001 From: Anthony Ramine Date: Thu, 6 Jun 2013 22:25:07 +0200 Subject: Silence a misleading warning with some comprehensions When compiling comprehensions with generators which are foldable to 'true', a misleading warning is emitted by sys_core_fold because a clause resulting from the compilation of the comprehension to Core Erlang is not marked as generated by the compiler. An example of such a comprehension is [ true || true ]. --- lib/compiler/src/v3_core.erl | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'lib/compiler/src') diff --git a/lib/compiler/src/v3_core.erl b/lib/compiler/src/v3_core.erl index eea54b30a2..f243127b66 100644 --- a/lib/compiler/src/v3_core.erl +++ b/lib/compiler/src/v3_core.erl @@ -956,7 +956,8 @@ lc_tq(Line, E, [Fil0|Qs0], Mc, St0) -> args=[], clauses=[#iclause{anno=LAnno,pats=[], guard=Gs,body=Lps ++ [Lc]}], - fc=#iclause{anno=LAnno,pats=[],guard=[],body=[Mc]}}, + fc=#iclause{anno=LAnno#a{anno=[compiler_generated|LA]}, + pats=[],guard=[],body=[Mc]}}, [],St2}; false -> {Lc,Lps,St1} = lc_tq(Line, E, Qs0, Mc, St0), @@ -1101,7 +1102,8 @@ bc_tq1(Line, E, [Fil0|Qs0], AccVar, St0) -> clauses=[#iclause{anno=LAnno, pats=[], guard=Gs,body=Bps ++ [Bc]}], - fc=#iclause{anno=LAnno,pats=[],guard=[],body=[AccVar]}}, + fc=#iclause{anno=LAnno#a{anno=[compiler_generated|LA]}, + pats=[],guard=[],body=[AccVar]}}, [],St}; false -> {Bc,Bps,St1} = bc_tq1(Line, E, Qs0, AccVar, St0), -- cgit v1.2.3
