Article title: gcc best compilation parameters. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. I. Version 1.2 (gcc 2.9.x) 　　 I386 (Intel), do you really want to install gentoo on that? CHOST = "i386-pc-linux-gnu" CFLAGS = "-march = i386-O3-pipe-fomit-frame-pointer" CXXFLAGS = "-march = i386-O3-pipe-fomit-frame-pointer" 　　 Isung (Intel), do you really want to

Detect the CPU, BIOS, motherboard (including chipset, motherboard slot, interface, etc.) of the computer, system manufacturer, chip, bus, equipment, etc. The CPU types that Windows Optimizer Master can detect are as follows: Intel Series: Core series, Pentium Extreme Edition, Pentium 4 Cedar Mill, Celeron D, Pentium M Yonah,

determine which product the processor belongs. For example, 6 Series INTEL processors include Pentium Pro, Pentium II, Pentium II Xeon, Pentium III and Pentium III Xeon processors. The 5th generation includes the Pentium processo

This article is separated from a programming instruction manual named Gentoo Linux, which is helpful for compiling programs. -------------------------------------------------------------------------------- I. version 1.2 (gcc 2.9.x) I386 (Intel), do you really want to install gentoo on that? CHOST = "i386-pc-linux-gnu"

Use the cpuid Assembly command (machine code: 0fh a2h, if your compiler does not support cpuid command, only emit machine code), this command can be recognized by the following CPU: More than 486 of Intel CPUs, CPU above cyrix M1, CPU above amd am486 (1) obtain the cpu oem string to determine the CPU vendor Let eax = 0 first, then call cpuid InEl CPU will return: EBX: 756e6547h 'genu'EdX: 49656e69h 'inei'ECX: 6c65746eh 'ntel'EBX, EDX, and ECX will be connected to genuineintel. The

algorithm was re-implemented using a combination of regular integer and fixed point arithmetic. images produced with integer version of the chroma key were abstrally identical to those created by a floating point one. the price was to reduce the working angle parameter range so that its tangent fit into reasonable fixed precision representation-this disallowed small and large angles and although did not present a problem for the test images, can be a potential problem. second problem is that th

Cflags =-March = i386-O3-pipe-fomit-frame-pointer Cxxflags + =-March = i386-O3-pipe-fomit-frame-pointer Isung (Intel ): Cflags =-March = ibench-O3-pipe-fomit-frame-pointerCxxflags + =-March = imo-- O3-pipe-fomit-frame-pointer Pentium 1 (Intel) Cflags =-March = Pentium-O3-pipe-fomit-frame-pointerCxxflags + =-March = Pentium-O3-pipe-fomit-frame-pointer

Check the memory information, CAT/proc/meminfo. Similarly, check the CPU information. CAT/proc/cpuinfo sometimes has such questions. For example, if the 4-core CPU is a 2-core CPU * dual-core, or 1 CPU * quad core? There is a simple method: the number of processor, the number of cores, and the number of CPUs, depending on the physical ID + 1 of the last Processor For example: processor : 0vendor_id : GenuineIntelcpu family : 6model : 23model name :

GCC compilation optimization settings-general Linux technology-Linux programming and kernel information. The following is a detailed description. Check your gcc version: # Gcc -- version * Obtain the cpu model: # Cat/proc/cpuinfo * Create the make. conf file under/etc/and write different content according to the cpu model (note that your gcc version must be above 3.0 ): I386 (Intel) CHOST = "i386-pc-linux-gnu" CFLAGS = "-march = i386-O3-pipe-fomit-frame-pointer" CXXFLAGS = "-march = i386-O

How can we optimize your system? The following is a simple and small method, but the optimization and adjustment of a system is far more than that. The performance needs to be adjusted according to actual needs. There is no way to meet all system requirements. 1. Check your gcc version:Note that your gcc version must be later than 3.0. # Gcc -- version 2. obtain your cpu model: Cat/proc/cpuinfo 3. Create the make. conf file under/etc/and write different contents according to the cpu model. ◆ I

mechanisms. 11.5.1 Cache control registers and bits Figure 11-3 depicts the Cache control mechanism in the IA-32 processor. Unlike the memory address space, these work in the same way as Intel 64 processor. The intel 64 and IA-32 architecture provides the following Cache control registers and bits to allow or restrict cache for various pages or regions in the memory: 1,CD flag, control register Cr0 bit 30-- Control the cache of the system memory location (see section 2.5 ). If the CD mark is

manufacturers. The Intel processor type identifier we typically use is "0", and the "0f24" CPUID is of this type.Family (series)The series identification can be used to determine the processor belongs to that generation of products. Intel processors such as the 6 series include Pentium Pro, Pentium II, Pentium II Xeon, Penti
