## Build
|
||
|
|
|
||
|
|
1. Configure the toolchain and additional options in `config.mk`:
|
||
|
|
```
|
||
|
|
# Supported: GCC, CLANG, ICC
|
||
|
|
TAG ?= GCC
|
||
|
|
ENABLE_OPENMP ?= false
|
||
|
|
|
||
|
|
OPTIONS += -DARRAY_ALIGNMENT=64
|
||
|
|
#OPTIONS += -DVERBOSE_AFFINITY
|
||
|
|
#OPTIONS += -DVERBOSE_DATASIZE
|
||
|
|
#OPTIONS += -DVERBOSE_TIMER
|
||
|
|
```
|
||
|
|
|
||
|
|
The verbosity options enable detailed output about affinity settings, allocation sizes and timer resolution.
|
||
|
|
|
||
|
|
|
||
|
|
2. Build with:
|
||
|
|
```
|
||
|
|
make
|
||
|
|
```
|
||
|
|
|
||
|
|
You can build multiple toolchains in the same directory, but notice that the Makefile is only acting on the one currently set.
|
||
|
|
Intermediate build results are located in the `<TOOLCHAIN>` directory.
|
||
|
|
|
||
|
|
To output the executed commands use:
|
||
|
|
```
|
||
|
|
make Q=
|
||
|
|
```
|
||
|
|
|
||
|
|
3. Clean up with:
|
||
|
|
```
|
||
|
|
make clean
|
||
|
|
```
|
||
|
|
to clean intermediate build results.
|
||
|
|
|
||
|
|
```
|
||
|
|
make distclean
|
||
|
|
```
|
||
|
|
to clean intermediate build results and binary.
|
||
|
|
|
||
|
|
4. (Optional) Generate assembler:
|
||
|
|
```
|
||
|
|
make asm
|
||
|
|
```
|
||
|
|
The assembler files will also be located in the `<TOOLCHAIN>` directory.
