From: "pinskia at gcc dot gnu dot org" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug optimization/13954] [tree-ssa] SRA does not work for classes that use inheritance Date: Sat, 31 Jan 2004 21:23:00 -0000 [thread overview] Message-ID: <20040131212356.29588.qmail@sources.redhat.com> (raw) In-Reply-To: <20040131211533.13954.dann@godzilla.ics.uci.edu> ------- Additional Comments From pinskia at gcc dot gnu dot org 2004-01-31 21:23 ------- Confirmed, the problem here is more complicated: Cannot scalarize variable param because it must live in memory Cannot scalarize variable local because it must live in memory Cannot scalarize variable MT.3 because it must live in memory The problem here is that: void copystruct1(teststruct) (param) { struct { double d; char f1; } * local.0; struct { double d; char f1; } * param.1; char T.2; { struct teststruct local; param.f1 = 0; local.0 = (struct { double d; char f1; } *)&local; param.1 = (struct { double d; char f1; } *)¶m; *local.0 = *param.1; { T.2 = local.f1; if (T.2 != 0) { { link_error (); } } else { } } } } Which means it does not using the right structs assigning or something werid is going on. -- What |Removed |Added ---------------------------------------------------------------------------- Severity|normal |enhancement Status|UNCONFIRMED |NEW Ever Confirmed| |1 Keywords| |pessimizes-code Last reconfirmed|0000-00-00 00:00:00 |2004-01-31 21:23:56 date| | Target Milestone|--- |tree-ssa http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13954
