Hello,
I made some preparations to support also clang in the new build system.
You can configure the compiler per BSP variant, e.g.
[riscv/rv32imac]
COMPILER = clang
# Flags passed to the library archiver
ARFLAGS = crD
# Warning flags passed to the C compiler
CC_WARNING_FLAGS = -Wmissing-prototypes -Wimplicit-function-declaration
-Wstrict-prototypes -Wnested-externs
I have now the following problem:
./waf configure --rtems-tools=/build/rtems/5,/usr
--rtems-options=rv32imac.ini
Setting top to : /home/EB/sebastian_h/git-rtems-5
Setting out to :
/home/EB/sebastian_h/git-rtems-5/build
Configure board support package (BSP) : riscv/rv32imac

File
/home/EB/sebastian_h/git-rtems-5/cpukit/score/cpu/riscv/riscv-exception-handler.S
has no mapping in ['.c', '.obj', '.o', '.pc.in'] (load a waf tool?)
Waf doesn't know how *.S files are turned into *.o files. What is the
clang assembler command? Is it missing in
