SSL Version: SNAP 20070618, 0.9.9-dev OS Version: linux-sparc32 Title: Bad .align directives generated by perl assembly generators on Sparc
I have confirmed that the assembly files generated for Sparc result in bad opcodes leading to run time illegal instructions. Assembly files generated by crypto/bn/sparc*pl generate lines .align 32 ;OK .align 32,0x1000000 ; BAD .align 16,0x1000000 ; BAD The last two are faulty - the intention is to fill the padded space with nop instruction 01 00 00 00. But the padding used is BYTE padding and hence the space is filled with 00 00 00 00, i.e, 0x1000000 is truncated to 0x00 and used as padding byte. Solution: assembler align directive should be .align 32 -OR- .align 16 It is not necessary to specify the nop padding as the assembler will fill it in correctly given the text .section directive. ______________________________________________________________________ OpenSSL Project http://www.openssl.org Development Mailing List [email protected] Automated List Manager [EMAIL PROTECTED]
