Sam Clegg	8e8cc34aad	Makefile: Don't mix phony targets with directory names Remove build rules for $(SYSROOT) and $(SYSROOT_INC). The latter becomes `include_dirs`. The former is not needed, instead just add startup_files to the finish rule.	6 years ago
vms	5ae626e99d	delete a space in predefined-macros.txt	6 years ago
vms	a64f654488	replace some macros with its builtins analogs	6 years ago
vms	2be6428b21	rename printf_no_Lf to __small_printf	6 years ago
Dan Gohman	51969495ee	Define TIME_UTC to be 1. TIME_UTC is the only time base defined by the relevant standards. This change doesn't preclude adding other time bases in the future.	6 years ago
Dan Gohman	1bdb356bef	Define CLOCKS_PER_SEC to have type clock_t. The C standard requires CLOCKS_PER_SEC to have type clock_t.	6 years ago
Dan Gohman	cf366c06d1	Optimize lseek in the `tell` case. `lseek(x, 0, SEEK_CUR)` has no effect other than to return the current file offset. The patch here uses a macro with `__builtin_constant_p` to recognize this case and rewrite it to a library call that uses `fd_tell` rather than `fd_seek`, so that programs that don't need actual seeking don't end up importing `fd_seek`. This is also the first usage of `__wasi_fd_tell` in WASI libc, so this adds it to undefined-symbols.txt.	6 years ago
Dan Gohman	9f103c2883	Say "wasm32-wasi" rather than "wasm32-unknown-wasi".	6 years ago
Dan Gohman	401012952d	Declare getentropy in <sys/random.h> Some systems, such as Darwin, only declare getentropy in <sys/random.h>, so declare it there on WASI too for compatibility. Also, give getentropy the underscore-prefix/weak-symbol treatment, as it's not a standard-reserved identifier.	6 years ago
Dan Gohman	9bb4cc5c41	Disable unused fields in FILE and __libc. Some of these fields are only needed for threads, some are not needed at all. Removing them helps prevent code from accidentally using them, such as when we merge in new musl versions.	6 years ago
Dan Gohman	2201343c17	Add vfwprintf.c to the printscan list. This causes the build to produce no-long-double and no-floating-point versions of this file, following what is done for vfprintf.c.	6 years ago
Dan Gohman	1cbedc6d7e	Implement FD_SET, FD_CLR, etc. Previously, FD_SET and friends were missing their actual definitions. This provides definitions, entirely within the system headers in a way that doesn't need instantiated out-of-line definitions.	6 years ago
Dan Gohman	538937e2c8	Remove capsicum.h; WASI libc doesn't support that API, even internally.	6 years ago
Dan Gohman	0df6243d52	Make calloc set ENOMEM when failing due to overflow. This fixes a bug in upstream dlmalloc, where it doesn't set errno to ENOMEM in overflow or footprint overrun cases.	6 years ago
Dan Gohman	972067b74b	Make the strerror message for ESUCCESS (0) be "Success". Previously it was "No error information", which was indistinguishable from an unrecognized errno value.	6 years ago
Dan Gohman	ad03c82d65	Implement reallocarray. reallocarray is non-standard but present in GLIBC and BSDs.	6 years ago
Dimitrii Nemkov	488c478b59	Update README.md	6 years ago
Jakub Konka	5ce487a789	Add missing asctime symbol	6 years ago
vms	4194578ae8	Fix floatscan no long double usage (#21) * fix long double using in floatscan * define separate macroses for copysignl, fmodl, and scalbnl instead of #ifndef	6 years ago
Dan Gohman	29d45024c7	Remove the Linux-specific <sys/signalfd.h> header.	6 years ago
Dan Gohman	49f1a57cb8	Declare getrusage. It's defined publicly in libc, so publicly declare it too.	6 years ago
Dan Gohman	ec9f1c3956	Format changes to musl code to fit musl's style. The whitespace diffs are converting from spaces to tabs.	6 years ago
Jakub Konka	03a1adbf2b	Fixes #20 Adds missing localtime.c source file to Makefile and to expected defined symbols list.	6 years ago
Pat Hickey	fa84763026	gitignore build	6 years ago
Pat Hickey	fad009dc1d	build: use LC_ALL=C for sorting LC_COLLATE doesn't seem to work with all `sort`s	6 years ago
Dan Gohman	1cc98f27f5	Update to cloudlibc 8835639f27fc42d32096d59d294a0bbb857dc368. There's no functional change here; the only change is the patch I submitted upstream, so we can remove some local changes.	6 years ago
Dan Gohman	f41256b602	Update to musl 1.1.22. Most of the changes are in threads, TLS, dynamic linking, and other features wasi doesn't yet use, but there are some bug fixes in code wasi does use. atanl.c - local changes no longer needed as they've now landed upstream. include/alltypes.h.in - Upstream now makes FILE a complete type in pre-C11 mode. For WASI, this level of pre-C11 strictness isn't as important, and having multiple incompatible definitions of _IO_FILE that are kept separate only by clever use of translation unit boundaries can confuse some tools, so stick with the incomplete type.	6 years ago
Dan Gohman	65107e782f	Rename README to README.md.	6 years ago
Dan Gohman	e18d69c801	Remove socket.c, which was a stub that always failed with ENOSYS.	6 years ago
Dan Gohman	ab594e4d51	Use the same indentation style as surrounding code.	6 years ago
Dan Gohman	7ba6adfc61	Fix miscellaneous lint warnings.	6 years ago
Dan Gohman	4646d29abc	Make basics include guard names more consistent.	6 years ago
Dan Gohman	ad22a59013	Add a basics implementation of <inttypes.h>. Musl's generic definitions for PRIxPTR and several others in <inttypes.h> are incorrect for wasm, so introduce a new <inttypes.h> and <__header_inttypes.h> in the basics module using compiler-provided definitions. Fixes #13.	6 years ago
Dan Gohman	9f0d8e85e3	Define _ALL_SOURCE when generating predefined-macros.txt. And clean up various stale declarations and macros that this turned up. In particular: - Don't install pthread.h or aio.h in THREAD_MODEL=single mode. - Don't define mkstemp and friends, since WASI currently has no support for temporary directories.	6 years ago
Dan Gohman	079d7bda78	Don't install <ucontext.h> or <sys/ucontext.h> for WASI. WASI doesn't support `getcontext`, `setcontext`, or related functions.	6 years ago
Dan Gohman	24792713d7	Fix uselocale to support non-default locales. Musl's locales implementation depends on pthreads. Since WASI libc doesn't yet have pthreads, it currently has alternate code for supporting locales. Previously, this code just assumed that it only had to support the default locale, however libc++ uses uselocale with non-default locals, so add support for that. With this, the C++ <iostream>-style hello world now works, with -fno-exceptions.	6 years ago
Dan Gohman	f74124a6f4	Filter out __FLT16_* macros from predefined-macros.txt. Whether these are defined or not depends on the version of clang in use, and they're not that important at this time, so for now just ignore them for the purposes of this testing output.	6 years ago
Dan Gohman	e5f14be383	Add comments explaining changes to upstream source files. Add at least a one-line comment on every `#ifdef __wasilibc_unmodified_upstream` briefly indicating what its purpose is. While here, reenable some of the code that was previously disabled when getenv wasn't supported, as getenv is now supported.	6 years ago
Dan Gohman	685d014446	Provide a public interface to preopened directory lookups. (#10) * Provide a public interface to preopened directory lookups. For users of especially non-C compilers, provide an API for looking up preopened directories. This is used internally in WASI libc to translate from eg. `open` to `openat`, but it can now also be used by user code.	6 years ago
Dan Gohman	320054e84f	WASI libc prototype implementation. This incoporates pieces from musl-libc, cloudlibc, cloudabi, libpreopen, and dlmalloc, as well as a significant amount of new code.	6 years ago
eliasbenali	0e98504240	Fix ssize_t redefinition mismatch. (#10) * Fix ssize_t redefinition mismatch. Align definition with comment and previous define in __typedef_ssize_t.h * Fix __typedef_ssize_t.h, redundancy in sys/types.h	6 years ago
Dan Gohman	78b6c3d875	Merge pull request #9 from WebAssembly/dlmalloc Add a malloc implementation using dlmalloc.	6 years ago
Dan Gohman	dbfccac2e4	Add a malloc implementation using dlmalloc.	6 years ago
