Generated test application (blechc -app) includes the blech program as .c file

[schorg]

The Blech compiler automatically generates a test program - blech.c by default - with the following command line

blechc --app --trace control.blc

Compiling all generated C-files generates duplicate symbol warnings.

cd blech
clang -Iinclude *.c

duplicate symbol '_blc_blech_01control01_init' in:
    /var/folders/l9/p0sgmsvj16v16tgzlplc3flm0000gn/T/blech-4471ee.o
    /var/folders/l9/p0sgmsvj16v16tgzlplc3flm0000gn/T/control-74f76a.o
... and so on

Reason: The EntryPoint file control.c is included as a control.c instead of control.h
into blech.c.

I am on it.

It is not a bug, it is a feature which, however, confuses even those who introduced it years ago ;-)

[schorg]

Can't remember the reason. Can you elaborate on this

[FriedrichGretz]

Before pushing to master, did you check all the code gen tests? With your commit all of them should be broken, if I remember correctly

[FriedrichGretz]

The test program and the blech.c are tightly coupled so instead of including the header and compiling to C files, we directly include the code and you only need to compile the test program. Additionally compiling the blech.c is what raised the warnings.

Created a branch for this. The issue creates problems when compiling the C code to WebAssembly. I will look into the code generation tests, before I do a pull request

Ah sorry, did not see the new branch when I clicked on the commit
