From: bugzilla-daemon@bugs.ecos.sourceware.org To: unassigned@bugs.ecos.sourceware.org Subject: [Bug 1001539] Single precision floating point math library Date: Sun, 09 Jun 2013 18:23:00 -0000 [thread overview] Message-ID: <bug-1001539-777-NPt08kW9Wo@http.bugs.ecos.sourceware.org/> (raw) In-Reply-To: <bug-1001539-777@http.bugs.ecos.sourceware.org/> Please do not reply to this email, use the link below. http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001539 --- Comment #35 from Ilija Kocho <ilijak@siva.com.mk> --- (In reply to comment #33) > Created attachment 2255 [details] > Inline some portable API functions for IEEE only option (incremental) > > Here is a proposal for optimisation of some functions for both space and > speed. If CYGSEM_LIBM_COMPAT_IEEE_ONLY compatibility option is selected then > portable API (wrapper) functions became trivial and can be inlined. Inlining Correction: it's ieee754-api, not portable-api! > eliminates one step of indirection, producing faster code. The generated > code in total, is also shorter. At present following portable APIs are > inlined: atan2/atan2f and hypot/hypotf. The reason for this selection is > that they are used by basic complex carg/cargf and cabs/cabsf operations > respectively. > Inlining option is user selectable and is disabled by default in order to > preserve backward compatibility > > Here we come to complex number support. My initial intention was to enable > only basic operations: argument, abs value, conjugation, real and imaginary > parts (some of them trivial/builtin). However it turned out that complete > complex library (taken from Newlib) compiled without warnings - almost > verbatim. Therefore I decided to submit complete complex library as well. > Most functions are unaltered - hence original copyright banners are > preserved. The ones that I have altered are (however trivial) different > enough to publish them under eCos licence. That includes: carg, cabs, conj, > creal and cimag - all double and float. > Arguably the complex support could be subject to a separate bug, but IMO it > fits here well in context of previous paragraph. It is easy to change the > topic of this bug accordingly. > > Note: This attachment is incremental to 1656+1657+1658 patch collection. It > does not contain complex functions body. That will be posted in a patch that > follows. > > Ilija -- You are receiving this mail because: You are the assignee for the bug.
