RE: [MiNT] M68020 bn_asm
Howard, I've been working on porting OpenSSL to the Palm and have most of it completed; and as such having 68K assembler versions is _extremely_ important. Otherwise, the implementation might very well be too slow to be usable on the Palm. So...keep up the good work! - Max On Tue, 19 Feb 2002, Howard Chu wrote: From the overwhelming lack of response I guess no one on this list cares about Motorola 68k implementations. Just a final note in case anyone is listening. The previous file I sent works fine, passes all the tests. I noticed that my use of roxl/roxr in the bn_add_words and bn_sub_words functions was a poor choice, so this version avoids those instructions. -- Howard Chu Chief Architect, Symas Corp.

On a 68030 the RSA/DSA test is over 4x faster than gcc -O3 code. I am releasing this version under the terms of the OpenSSL license. thanks, I will test it on linux-m68k as soon as my CPU will have a few spare cycles. One thing I have noted, you use the 64 bit variants of mul/div in many places. This will probbaly make the code much slower than gcc generated code on 68060 CPUs as they do not implemente this insns in hardware and need to emulate them in the OS.

Re: OpenSSL on WinCE
I'm almost ready to release static libs for Palmhehe.. (sorry, there's this growing feud here @ work between Palm and PocketPC). - Max On Fri, 11 Jan 2002, Devaraj Das wrote: Hi folks, I am new to this group.

Test Fail in BN_mod_mul
Hi All, I'm working on porting OpenSSL to the PalmOS platform (the SSLeay port just doesn't work for me for a number of reasons). Anyway, i've gotten many pieces of crypto to test OK, and all of bignum except for the BN_mod_mul test, which fails only after quite a number of iterations: This is the line that crashes - line 401 of bn_asm.c (bn_sub_words): r[1]=(t1-t2-c)BN_MASK2; I get essentially an error that says that memory has been accessed that hasn't been allocated or is out of bounds. Here's the variable dump: a: 0x00036E02 b: 0x0003DC2 c: 0 n: 15 r: 0x00036FC2 t1: 354005811 t2: 14090239 Also: i=55 in line 748 (if (!BN_mod_mul(e,a,b,c,ctx))) of bntest.c when it crashes. If you want, I can provide variable dumps for the other levels in the stack as well. All of the rest of the Bignum tests pass (including those past the mod_mul test), and i'm at a bit of a loss as to why this one fails. Any ideas? - Max __ OpenSSL Project http://www.openssl.org Development Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
