System:
IA-64, SuSE SLES-8
Compiler:
Intel(R) C++ Itanium(R) Compiler for Itanium(R)-based applications
Version 7.0, Build 20021210
I've patched the Configure script by adding a new configuration,
"linux-ia64-ecc". It's based on the "linux-ia64" configuration with
the following changes:
Compiler executable changed from "gcc" to "ecc"
The Intel compiler is /opt/intel/compiler70/ia64/bin/ecc
Deleted "-fomit-frame-pointer" option
As far as I can tell from the documentation, the behavior
specified by gcc's "-fomit-frame-pointer" option is the
default behavior for ecc.
Changed "-O3" to "-O2"
Experiment shows that with "-O3", "make test" fails with:
test BN_sqr
Square test failed!
This seems to be an instance of the problem described at
<http://www.openssl.org/support/faq.html#BUILD11>.
I've provided a context diff for Configure as an attachment.
Also, one of the compiler warnings points to a possible bug. The file
crypto/mem_clr.c contains the following:
cleanse_ctr += (17 + (unsigned char)((int)p & 0xF));
where p is an unsigned char*. The cast of p to type int will lose
significant bits, since int is 32 bits and pointers are 64 bits.
I don't know of any symptoms of this bug; in particular, casting to
unsigned long rather than int doesn't fix the BN_sqr problem.
Please let me know if you need more information.
