• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description Attila Tóth 2008-03-28 15:27:08 UTC]

This one is closely related to bug 175627, IMHO.

Reopen with some errors and emerge --info output.

Here is the problematic code that is using the pic register directly. Ever other register is used/abused as well. compile with nopie.. 



#ifdef __GNUC__
    ".att_syntax prefix;"
    AS2(    mov %0, %%ebx)
        : "=m" (temp)
        : "m" (m_L1KeyLength), "c" (blocksRemainingInWord64), "S" (data), "D" (nhK+tagPart*2), "d" (m_isFirstBlock), "a" (polyS+tagPart*4)
        : "memory", "cc"
    );
#endif



make CXXFLAGS=-fno-pie LDFLAGS=-nopie  ; #worked for me.
being that there is not a single free register there is little to 
nothing we can do to fix it. You can ask upstream to not use the pic register.

Yes. Fortunately I don't need amule, so I removed the library and the application.

Done.
