# NOTE: Using types such as uint8_t without stdint.h is not portable. ~ahill

# NOTE: LLVM loves yelling about unqualified std calls, so we'll just fix them
|

# so we can properly troubleshoot why this doesn't work. ~ahill

# NOTE: mrustc passes -fno-tree-sra to the GCC to work around a bug that is
|
||||
# present when it comes to linking, however clang has no idea what that
|
||||
# means. ~ahill
|
||||
# NOTE: mrustc converts Rust's asm! macro into inline Assembly in C, which seems
|
||||
# to work on GCC, but is broken on LLVM. Using the input constraint "0"
|
||||
# with the output constraint prefix "+" causes an error. Substituting "+"
|
||||
# with "=" seems to fix this problem. ~ahill
|
||||
# NOTE: mrustc forces the system to link with libatomic because it's assuming
|
||||
# that libgcc exists, even though it doesn't in this case. compiler-rt
|
||||
# supplies the functionality we need, so this is not required. ~ahill
|
||||
# NOTE: Rather than completely disabling optimizations, which causes rustc to
|
||||
# become incredibly slow, we simply prevent it from optimizing null

# pointer checks out (-fno-delete-null-pointer-checks). I'm not sure why

# this behavior would be desired, but someone likely has a valid use case.
