From aeeae06a79815dc190061534d47236cec09f9e32 Mon Sep 17 00:00:00 2001 From: ryker <> Date: Mon, 5 Oct 1998 20:13:14 +0000 Subject: Import of SSLeay-0.9.0b with RSA and IDEA stubbed + OpenBSD build functionality for shared libs. Note that routines such as sslv2_init and friends that use RSA will not work due to lack of RSA in this library. Needs documentation and help from ports for easy upgrade to full functionality where legally possible. --- src/lib/libcrypto/perlasm/readme | 124 +++++++++++++++++++++++++++++++++++++++ 1 file changed, 124 insertions(+) create mode 100644 src/lib/libcrypto/perlasm/readme (limited to 'src/lib/libcrypto/perlasm/readme') diff --git a/src/lib/libcrypto/perlasm/readme b/src/lib/libcrypto/perlasm/readme new file mode 100644 index 0000000000..f02bbee75a --- /dev/null +++ b/src/lib/libcrypto/perlasm/readme @@ -0,0 +1,124 @@ +The perl scripts in this directory are my 'hack' to generate +multiple different assembler formats via the one origional script. + +The way to use this library is to start with adding the path to this directory +and then include it. + +push(@INC,"perlasm","../../perlasm"); +require "x86asm.pl"; + +The first thing we do is setup the file and type of assember + +&asm_init($ARGV[0],$0); + +The first argument is the 'type'.
