There's a new program named ape/ape-m1.c which will be used to build an embeddable binary that can load ape and elf executables. The support is mostly working so far, but still chasing down ABI issues.

# ANSI Mode
|
|
#
|
|
# These flags cause GCC to predefine __STRICT_ANSI__. Please be warned
|
|
# that Cosmopolitan headers are written to comply with that request if
|
|
# it's possible to do so. Consider the following example:
|
|
#
|
|
# make -j12 -O o//tool/viz/printvideo.i
|
|
# clang-format-10 -i o//tool/viz/printvideo.i
|
|
# less o//tool/viz/printvideo.i
|
|
#
|
|
# You'll notice functions like memcpy(), ioctl(), etc. get expanded into
|
|
# wild-eyed gnu-style performance hacks. You can turn it off as follows:
|
|
#
|
|
# make -j12 -O MODE=ansi o/ansi/tool/viz/printvideo.i
|
|
# clang-format-10 -i o/ansi/tool/viz/printvideo.i
|
|
# less o/ansi/tool/viz/printvideo.i
|
|
#
|
|
# Here it becomes clear that ANSI mode can help you decouple your source
|
|
# from Cosmopolitan, by turning it into plain ordinary textbook C code.
|
|
#
|
|
# Another potential use case is distributing code to folks using tools
|
|
# such as MSVC or XCode. You can run your binary objects through a tool
|
|
# like objconv to convert them to COFF or MachO. Then use ANSI mode to
|
|
# rollup one header file that'll enable linkage with minimal issues.
