WASM_CC ?= clang
Allow user to provide CC wrapper (#255) If using a custom toolchain not on the path, explicitly invoking ccache/sccache is required (also easier to debug that the right compiler is being invoked). Fixes #253.

WASM_AR ?= $(patsubst %clang,%llvm-ar,$(filter-out ccache sccache,$(WASM_CC)))
Revamp and simplify the libpreopen code. (#110) wasi-libc's copy of libpreopen has evolved so many local changes that it's no longer worth keeping the upstream code structure and marking changes with __wasilibc_unmodified_upstream. This PR merges the source files into a single file, removes all __wasilibc_unmodified_upstream code, eliminates the ability to allocate multiple preopen lists, eliminates the need for __wasilibc_init_preopen, eliminates the non-standard eaccess, and makes several other cleanups. It also enables NDEBUG so that internal assertions are disabled in release builds.

THREAD_MODEL ?= single
Add build flag to select malloc implementation Add a build flag MALLOC_IMPL that can be set to dlmalloc or none (defaulting to dlmalloc) which controls the malloc implementation to use. The dlmalloc option is the same as before, but selecting none removes dlmalloc from the libc build. This flag replaces the BUILD_DLMALLOC flag, which never worked and thus can be removed without breaking any builds. By switching to MALLOC_IMPL, there is a clear path towards a different heap implementation, such as mimalloc.

Add basic emulation of getcwd/chdir (#214) * Add basic emulation of getcwd/chdir This commit adds basic emulation of a current working directory to wasi-libc. The `getcwd` and `chdir` symbols are now implemented and available for use. The `getcwd` implementation is pretty simple in that it just copies out of a new global, `__wasilibc_cwd`, which defaults to `"/"`. The `chdir` implementation is much more involved and has more ramification, however. A new function, `make_absolute`, was added to the preopens object. Paths stored in the preopen table are now always stored as absolute paths instead of relative paths, and initial relative paths are interpreted as being relative to `/`. Looking up a path to preopen now always turns it into an absolute path, relative to the current working directory, and an appropriate path is then returned. The signature of `__wasilibc_find_relpath` has changed as well. It now returns two path components, one for the absolute part and one for the relative part. Additionally the relative part is always dynamically allocated since it may no longer be a substring of the original input path. This has been tested lightly against the Rust standard library so far, but I'm not a regular C developer so there's likely a few things to improve! * Amortize mallocs made in syscalls * Avoid size bloat on programs that don't use `chdir` * Add threading compat * Collect `link`/`renameat` second path lookup * Update comments about chdir.c in makefile * Move definition of `__wasilibc_find_relpath_alloc` to header * Expand comments * Document the format of strings a bit more * Fixup a few issues in path logic * Fix GitHub Actions

LIBWASI_EMULATED_MMAN_SOURCES = \
$(shell find $(LIBC_BOTTOM_HALF_DIR)/mman -name \*.c)
Emulate `clock`, `times`, and `getrusage` using the monotonic clock. Upcoming WASI snapshots omit the `PROCESS_CPUTIME` clock, since WASI has no inherent concept of processes, and since implementations which don't use a process for each instance don't have a way to implement it efficiently. However, `clock`, `times`, and `getrusage` are useful functions, so provide optional emulated version of them, using the `MONOTONIC` clock. This means these implementations will measure not just the program's own CPU time, but also time spent suspended while other programs are running. Due to this difference in behavior, put these implementations behind a flag. Users must pass `-D_WASI_EMULATED_PROCESS_CLOCK` and link with `-lwasi-emulated-process-clocks` to enable them.

Emulate `clock`, `times`, and `getrusage` using the monotonic clock. Upcoming WASI snapshots omit the `PROCESS_CPUTIME` clock, since WASI has no inherent concept of processes, and since implementations which don't use a process for each instance don't have a way to implement it efficiently. However, `clock`, `times`, and `getrusage` are useful functions, so provide optional emulated version of them, using the `MONOTONIC` clock. This means these implementations will measure not just the program's own CPU time, but also time spent suspended while other programs are running. Due to this difference in behavior, put these implementations behind a flag. Users must pass `-D_WASI_EMULATED_PROCESS_CLOCK` and link with `-lwasi-emulated-process-clocks` to enable them.

Use separate makefile var for CFLAGS (#226) CFLAGS now get initialized with the provided value for WASM_CFLAGS, or its default. This seems to be the intended use case of having `WASM_CFLAGS ?=` at the top of the Makefile. Otherwise, if WASM_CFLAGS is set on the command line, it overrides all CFLAGS and for example `--sysroot` is not added, rendering the build invalid unless it is supplied on the make command line.

Emulate `clock`, `times`, and `getrusage` using the monotonic clock. Upcoming WASI snapshots omit the `PROCESS_CPUTIME` clock, since WASI has no inherent concept of processes, and since implementations which don&#39;t use a process for each instance don&#39;t have a way to implement it efficiently. However, `clock`, `times`, and `getrusage` are useful functions, so provide optional emulated version of them, using the `MONOTONIC` clock. This means these implementations will measure not just the program&#39;s own CPU time, but also time spent suspended while other programs are running. Due to this difference in behavior, put these implementations behind a flag. Users must pass `-D_WASI_EMULATED_PROCESS_CLOCK` and link with `-lwasi-emulated-process-clocks` to enable them.

Add build flag to select malloc implementation Add a build flag MALLOC_IMPL that can be set to dlmalloc or none (defaulting to dlmalloc) which controls the malloc implementation to use. The dlmalloc option is the same as before, but selecting none removes dlmalloc from the libc build. This flag replaces the BUILD_DLMALLOC flag, which never worked and thus can be removed without breaking any builds. By switching to MALLOC_IMPL, there is a clear path towards a different heap implementation, such as mimalloc.

Makefile refactoring; NFC (#186) * Use ?= for variables intended to be overridable. * Use `override` consistently for variables not meant to be overridden. * Omit miscellaneous comments from the build output. * Tidy up some comments. * Use `addprefix` to factor out a common prefix. * Add a comment. * Reorganize. * Adjust indentation. * Simplify the logic for the `check` rule. * Remove the `override` keywords. They theoretically protect what the Makefile considers to be implementation details from being overridden on the command-line, but in practice this isn&#39;t super important, and they add a lot of clutter. * Put source file names on their own lines.
