Hi !
I am currently working on an gentoo ebuild for maxdb 7.6.0.16.
As gentoo developers decided to switch to gcc version 3.4.4 i am also
switching the build process of maxdb to gcc 3.4.4.
For a complete build i had to change the following files:
src/SAPDB/RunTime/System/RTESys_AtomicOperation.c
src/SAPDB/RunTime/Communication/RTEComm_URIBuilder.hpp
src/SAPDB/Interfaces/Runtime/Util/IFRUtil_LinkedList.h
src/SAPDB/ServerTasks/SrvTasks_JobList.hpp
src/SAPDB/DataAccess/Data_ChainSplitSpaceBackwardRead.hpp
src/SAPDB/DataAccess/Data_ChainSplitSpaceForwardRead.hpp
I will of course send the patches as soon as i have a complete build,
but for now i need help with the file RTESys_AtomicOperation.c.
The compiler gives the following errors:
RTESys_AtomicOperation.c fast
RTESys_AtomicOperation.c: In function `RTESys_CmpxchgInt8':
RTESys_AtomicOperation.c:383: Fehler: PIC-Register »ebx« wird in »asm«
zerstört
RTESys_AtomicOperation.c: In function `RTESys_CmpxchgUInt8':
RTESys_AtomicOperation.c:435: Fehler: PIC-Register »ebx« wird in »asm«
zerstört
As my assembler programming is a bit rusty (last used on a VAX 18 years
ago) i cannot correct the cause of the error that is in the following
assembler code:
...
__asm__ __volatile__ (
"push %%ebx\n\t"
"movl %3, %%eax\n\t"
"movl %4, %%edx\n\t"
"movl %1, %%ebx\n\t"
"movl %2, %%ecx\n\t"
"lock; cmpxchg8b %0\n\t"
"movl %%edx, %6\n\t"
"movl %%eax, %5\n\t"
"pop %%ebx\n\t"
:
: "m"(*memoryPosition),
"m"(newValue),
"m"(resultLow),
"m"(expectedValue),
"m"(resultHigh),
"m"(resultLow),
"m"(resultHigh)
: "eax", "ebx", "ecx", "edx", "memory"
);
Can someone provide help with this ?
thanks - Hermann
