I am going to install ClamAV on an Itanium2(IA-64). I found that gcc have dedicated compile options for different platform. I am just quite interested to know if any of these options can make clamav more efficient (faster ?) on IA-64?
The full sets of IA-64 options can be found at: http://gcc.gnu.org/onlinedocs/gcc/IA-64-Options.html#IA-64%20Options
Anyone have idea about this?
I have lists some of the possible options below:
|-mno-volatile-asm-stop| Generate (or don't) a stop bit immediately before and after volatile asm statements. || || |-mno-sdata|
|-msdata| Disable (or enable) optimizations that use the small data section. This may be useful for working around optimizer bugs. || |-minline-float-divide-min-latency| Generate code for inline divides of floating point values using the minimum latency algorithm. |-minline-float-divide-max-throughput| Generate code for inline divides of floating point values using the maximum throughput algorithm. |-minline-int-divide-min-latency| Generate code for inline divides of integer values using the minimum latency algorithm. |-minline-int-divide-max-throughput| Generate code for inline divides of integer values using the maximum throughput algorithm.
|-mfixed-range=|register-range||
Generate code treating the given register range as fixed registers.
A fixed register is one that the register allocator can not use.
This is useful when compiling kernel code. A register range is
specified as two registers separated by a dash. Multiple register
ranges can be specified separated by a comma.
|-mearly-stop-bits|
|-mno-early-stop-bits|
Allow stop bits to be placed earlier than immediately preceding the
instruction that triggered the stop bit. This can improve
instruction scheduling, but does not always do so.
