icc/icpc intel compiler ürününde aşağıdaki g ++ komutunun bir karşılığı var mı? Bana şu çıktıyı verdiIntel ICC derleyicisinde hangi derleme seçeneklerinin etkin olduğunu nasıl görebilirim?

?> g++ -march=native -m32 ... -Q --help=target

Bu/g ++ seçenek bana gibi yararlı birçok bilgi vermek gcc: marchnehalem olduğunu m32 ve msse4.2enabled olduğunu mfpmath olduğunu 387, masm, att, ect ...

Intel icc/icpc derleyici için böyle bir seçenek olup olmadığını bilmek istiyorum.

Teşekkürler.

Soru, gösterilen seçenekler için g ++ 'dan gelen çıktıyı içeriyorsa daha iyi olurdu. – unwind

Ekledim, tavsiye için teşekkürler (+1). –

GCC seçeneğini kullanmayı tercih ediyorum '-v':' $ gcc -v test.c' gibi bir şey yazdıracaktır: '/usr/lib/gcc/x86_64-unknown-linux-gnu/5.3.0/cc1 -quiet -v ac -march = sandybridge -mmmx -mno-3dnow -msse ... '. Belki de icc'de çalışır? – rodrigo

aşağıdaki şekilde deneyebilirsiniz:

icpc -dM -E -x c++ *.c 

seçenekleri ile kombine eski:

-vec-report[=n] 
      control amount of vectorizer diagnostic information 
      n=0 no diagnostic information 
      n=1 indicate vectorized loops (DEFAULT when enabled) 
      n=2 indicate vectorized/non-vectorized loops 
      n=3 indicate vectorized/non-vectorized loops and prohibiting 
        data dependence information 
      n=4 indicate non-vectorized loops 
      n=5 indicate non-vectorized loops and prohibiting data 
        dependence information 
      n=6 indicate vectorized/non-vectorized loops with greater 
        details and prohibiting data dependence information 
      n=7 indicate vector code quality message ids and data values 
        for vectorized loops 

-qopt-report[=n] 
      generate an optimization report. Default destination is 
      <target>.optrpt. Levels of 0 - 5 are valid. 
      Please see documentation for additional details of 
      information provided by phase per level. 
      0 disable optimization report output 
      2 DEFAULT when enabled 

-qopt-report-file=[stdout | stderr | <file>] 
      specify the filename or output stream for the generated report 

-qopt-report-stdout 
      specify the generated report should be directed to stdout 

-qopt-report-per-object 
      specify the generated report should be directed to a .optrpt file 
      in the output directory (DEFAULT when another destination for the 
    report is not specified) 

-qopt-report-phase=<phase>[,<phase>,...] 
      specify one or more phases that reports are generated against 

-qopt-report-routine=<name>[,<name>,...] 
      restrict the report to routines containing the given name 

-qopt-report-filter=<string> 
      restricts the opt-report to specific files, routines or line 
      number ranges. Refer to the documentation for the specific 
      syntax of parameter string. 

-qopt-report-format=[text|vs] 
      specify the output format to be used for the opt-report as either 
      plain text or a format for use in the Microsoft* Visual Studio IDE 

-q[no-]opt-report-embed 
      When enabled, if an assembly file is being generated, special loop 
      info annotations will be emitted in the assembly file. If an object 
      file/executable is being generated, these will be emitted into the 
      object file/executable for use by the Intel VTune Amplifier 
      application. Automatically enabled when symbolic debug information 
      is enabled. 

-qopt-report-help 
      display the optimization phases available for reporting 

-qopt-report-names=<keyword> 
      Specifies whether mangled or unmangled names should appear in the 
      optimization report. 
      mangled - use mangled names 
      unmangled - use unmangled names (DEFAULT) 

-tcheck [mode] 
      enable analysis of threaded applications (requires Intel(R) Thread 
      Checker; cannot be used with compiler alone) 
      tci - instruments a program to perform a thread-count-independent 
        analysis 
    tcd - instruments a program to perform a thread-count-dependent 
        analysis (DEFAULT when mode is not used) 
      api - instruments a program at the api-imports level 

-tcollect[=<lib>] 
      inserts instrumentation probes calling the Intel(R) Trace Collector 
      API. The library -l<lib> is linked in the default being -lVT 
      (requires Intel(R) Trace Collector) 

-tcollect-filter file 
      Enable or disable the instrumentation of specified functions. 
      (requires Intel(R) Trace Collector) 

Bilgi enought sağlayacaktır. Umarım bu yardımcı olur.
