File embedding

Add feature embed and specify sources to be embedded with embed_source

bld.new_task_gen(features = 'cxx cprogram embed', embed_source = 'data/test.embed', ...)

In your .cpp-file add the following symbols:

extern unsigned char TEST_EMBED[];
extern uint32_t TEST_EMBED_SIZE;

The symbol is the filename without path. Dots are replaced with underscore.

Memory profiling

Run dmengine_memprofile.sh instead of dmengine.

To enable tracing where every allocation is written to disk for analaysis:

# DMMEMPROFILE_TRACE=1 dmengine_memprofile.sh

Create a trace report using memprofile.sh

memprofile.sh `which dmengine` memprofile.trace > report.html
