From: "john32979 at hotmail dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug target/13297] New: in x86 target -msoft_float should imply -mno-fp-ret-in-387 Date: Thu, 04 Dec 2003 08:32:00 -0000 [thread overview] Message-ID: <20031204083203.13297.john32979@hotmail.com> (raw) If -msoft_float is used to generate hooks for linking to FP emulation library, the results and arguments and results are still passed via the x87 stack if - mno-fp-ret-in-387 is not defined as well. This will generate invalid code for many embedded x86 platforms that do not have an FPU (e.g. AMD SC420). -msoft_float should imply -mno-fp-ret-in-387 to avoid confusion. At the bare minimum, a note regarding switching on -mno-fp-ret-in-387 in conjunction with - msoft_float when developing on FPU-less platforms should be mentioned. -- Summary: in x86 target -msoft_float should imply -mno-fp-ret-in- 387 Product: gcc Version: 3.2.1 Status: UNCONFIRMED Severity: enhancement Priority: P2 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: john32979 at hotmail dot com CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13297
