icc / icpc intel编译器上是否有以下g ++命令？
?> g++ -march=native -m32 ... -Q --help=target

这个gcc / g ++选项给了我很多有用的信息，比如：
m32和msse4.2为enabled，
march是nehalem，
mfpmath是387，
masm是att，等等......
我真的很想知道英特尔icc / icpc编译器是否存在类似的选项。
感谢。

您可以尝试如下：
icpc -dM -E -x c++ *.c
前者与选项结合：
-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)
将为您提供信息。我希望这会有所帮助。
