98859c885e std/fmt.zig: Pass full options struct to all internal functions 
The fill specifier is now handled in some cases. The default fill of '0'
is now ' ' for integers and non-byte sequences.

passing the error return trace async function test 2019-08-06 18:29:56 -04:00
Andrew Kelley

async functions have error return traces where appropriate 
however the traces are not merged on `await` or async function calls
yet.

When an async function has an error set or error union as its return
type, it has a `StackTrace` before the args in the frame, so that it is
accessible from `anyframe->T` awaiters. However when it does not have an
errorable return type, but it does call or await an errorable, it has a
stack trace just before the locals. This way when doing an `@asyncCall`
on an async function pointer, it can populate the args (which are after
the `StackTrace`) because it knows the offset of the args based only on
the return type.

This sort of matches normal functions, where a stack trace pointer could
be supplied by a parameter, or it could be supplied by the stack of the
function, depending on whether the function itself is errorable.

fix usingnamespace 
It used to be that usingnamespace was only allowed at top level. This
made it OK to put the state inside the AST node data structure. However,
now usingnamespace can occur inside any aggregate data structure, and
therefore the state must be in the TopLevelDeclaration rather than in
the AST node.

There were two other problems with the usingnamespace implementation:

 * It was passing the wrong destination ScopeDecl, so it could cause an
   incorrect error such as "import of file outside package path".
 * When doing `usingnamespace` on a file that already had
   `pub usingnamespace` in it would "steal" the usingnamespace, causing
   incorrect "use of undeclared identifier" errors in the target file.

11526b6e9d breaking: Add positional, precision and width support to std.fmt 
This removes the odd width and precision specifiers found and replacing
them with the more consistent api described in #1358.

Take the following example:

    {1:5.9}

This refers to the first argument (0-indexed) in the argument list. It
will be printed with a minimum width of 5 and will have a precision of 9
(if applicable).

Not all types correctly use these parameters just yet. There are still
some missing gaps to fill in. Fill characters and alignment have yet to
be implemented.

fce2d2d18b stage1: add support for @mulAdd fused-multiply-add for floats and vectors of floats 
Not all of the softfloat library is being built....

Vector support is very buggy at the moment, but should work when the bugs are fixed.
(as I had the same code working with another vector function, that hasn't been merged yet).

stage2 translate-c: implement functions with no prototype 
stage1 translate-c actually has this wrong. When exporting a function,
it's ok to use empty parameters. But for prototypes, "no prototype"

that the child type of the pointer only have one possible value

fix thread local variables for non- position independent code 
This fixes comes thanks to Rich Felker from the musl libc project,
who gave me this crucial information:

"to satisfy the abi, your init code has to write the same value
to that memory location as the value passed to the [arch_prctl]
syscall"

This commit also changes the rules for when to build statically
by default. When building objects and static libraries, position
independent code is disabled if no libraries will be dynamically
linked and the target does not require position independent code.

add docs for assembly and fix global assembly parsing 
Previously, global assembly was parsed expecting it to have
the template syntax. However global assembly has no inputs,
outputs, or clobbers, and thus does not have template syntax.
This is now fixed.

This commit also adds a compile error for using volatile
on global assembly, since it is meaningless.

breaking changes to std.mem.Allocator interface API 
Before, allocator implementations had to provide `allocFn`,
`reallocFn`, and `freeFn`.

Now, they must provide only `reallocFn` and `shrinkFn`.
Reallocating from a zero length slice is allocation, and
shrinking to a zero length slice is freeing.

When the new memory size is less than or equal to the
previous allocation size, `reallocFn` now has the option
to return `error.OutOfMemory` to indicate that the allocator
would not be able to take advantage of the new size.

For more details see #1306. This commit closes #1306.

This commit paves the way to solving #2009.

This commit also introduces a memory leak to all coroutines.
There is an issue where a coroutine calls the function and it
frees its own stack frame, but then the return value of `shrinkFn`
is a slice, which is implemented as an sret struct. Writing to
the return pointer causes invalid memory write. We could work
around it by having a global helper function which has a void
return type and calling that instead. But instead this hack will
suffice until I rework coroutines to be non-allocating. Basically
coroutines are not supported right now until they are reworked as
in #1194.

breaking changes to zig build API and improved caching 
* in Zig build scripts, getOutputPath() is no longer a valid function
   to call, unless setOutputDir() was used, or within a custom make()
   function. Instead there is more convenient API to use which takes
   advantage of the caching system. Search this commit diff for
   `exe.run()` for an example.
 * Zig build by default enables caching. All build artifacts will go
   into zig-cache. If you want to access build artifacts in a convenient
   location, it is recommended to add an `install` step. Otherwise
   you can use the `run()` API mentioned above to execute programs
   directly from their location in the cache. Closes #330.
   `addSystemCommand` is available for programs not built with Zig
   build.
 * Please note that Zig does no cache evicting yet. You may have to
   manually delete zig-cache directories periodically to keep disk
   usage down. It's planned for this to be a simple Least Recently
   Used eviction system eventually.
 * `--output`, `--output-lib`, and `--output-h` are removed. Instead,
   use `--output-dir` which defaults to the current working directory.
   Or take advantage of `--cache on`, which will print the main output
   path to stdout, and the other artifacts will be in the same directory
   with predictable file names. `--disable-gen-h` is available when
   one wants to prevent .h file generation.
 * `@cImport` is always independently cached now. Closes #2015.
   It always writes the generated Zig code to disk which makes debug
   info and compile errors better. No more "TODO: remember C source
   location to display here"
 * Fix .d file parsing. (Fixes the MacOS CI failure)
 * Zig no longer creates "temporary files" other than inside a
   zig-cache directory.

This breaks the CLI API that Godbolt uses. The suggested new invocation
can be found in this commit diff, in the changes to `test/cli.zig`.

first class support for compiling C code 
New CLI parameter: --c-source [options] [file]

It even works with `--cache on` when there are transitive dependencies.

Instead of `builder.addCExecutable`, use `builder.addExecutable` and pass
`null` for the root source file. Then use `builder.addCSourceFile`,
which takes the path to the C code, and a list of C compiler args.
Be sure to linkSystemLibrary("c") if you want libc headers to be
available.
