# About
**resolve-march-native** is a small command line tool to resolve
`-march=native` into explicit GCC or (experimental!) Clang flags.
# Example
```console
$ resolve-march-native --vertical
-march=sandybridge
-maes
--param=l1-cache-line-size=64
--param=l1-cache-size=32
--param=l2-cache-size=3072
```
```console
$ resolve-march-native --clang --vertical
-march=sandybridge
-Xclang -target-feature -Xclang +64bit
-Xclang -target-feature -Xclang +aes
-Xclang -target-feature -Xclang +avx
-Xclang -target-feature -Xclang +cmov
-Xclang -target-feature -Xclang +crc32
-Xclang -target-feature -Xclang +cx16
-Xclang -target-feature -Xclang +cx8
-Xclang -target-feature -Xclang +fxsr
-Xclang -target-feature -Xclang +mmx
-Xclang -target-feature -Xclang +pclmul
-Xclang -target-feature -Xclang +popcnt
-Xclang -target-feature -Xclang +sahf
-Xclang -target-feature -Xclang +sse
-Xclang -target-feature -Xclang +sse2
-Xclang -target-feature -Xclang +sse3
-Xclang -target-feature -Xclang +sse4.1
-Xclang -target-feature -Xclang +sse4.2
-Xclang -target-feature -Xclang +ssse3
-Xclang -target-feature -Xclang +xsave
-Xclang -target-feature -Xclang +xsaveopt
```
# Usage
```console
$ COLUMNS=80 resolve-march-native --help
usage: resolve-march-native [-h] [--debug] [--clang [COMMAND] | --gcc
[COMMAND]] [--vertical] [--keep-minus-features]
[--keep-identical-mtune] [--keep-mno-flags]
[--add-recommended] [--version]
options:
-h, --help show this help message and exit
--debug enable debugging (default: disabled)
--clang [COMMAND] [EXPERIMENTAL] target Clang (default: target GCC) and
use given command if any (default: clang)
--gcc [COMMAND] target GCC explicitly and use given command if any
(default: gcc))
--vertical produce vertical output (default: horizontal output)
--add-recommended, -a
add recommended flags (default: not added)
--version show program's version number and exit
Clang-related arguments:
--keep-minus-features
keep "-target-feature -*" style parameters (default:
stripped away)
GCC-related arguments:
--keep-identical-mtune
keep implied -mtune=... despite architecture identical
to -march=... (default: stripped away)
--keep-mno-flags keep -mno-* parameters (default: (superfluous ones)
stripped away)
