* improve error message when build manifest file is missing
* update std.zig.Ast to support ZON
* Compilation.AllErrors.Message: make the notes field a const slice
* move build manifest parsing logic into src/Manifest.zig and add more
checks, and make the checks integrate into the standard error
reporting code so that reported errors look sexy
closes#14290
* std.zig.parse is moved to std.zig.Ast.parse
* the new function has an additional parameter that requires passing
Mode.zig or Mode.zon
* moved parser.zig code to Parse.zig
* added parseZon function next to parseRoot function
This commit makes the text more dense with sources, noes the outstanding
audit and adds an explanation of the table before converting everything
to markdown tables.
For the status a checkmark or cross in utf8 encoding are used and the
input and output sizes of all operations are given inclusive comments for
understanding of the routines.
This should document all compiler_rt integer and float routines, but
does not include a documentation of existing ieee floating and math
routines.
this patch is from upstream, to fix -Wdeprecated-non-prototypes issues.
K&R-style has apparently been deprecated since even C89, and C2x will be
repurposing the syntax space. this warning triggers when the change would
affect the meaning of the code.
Unfortunately, due to the Windows equivalent of executable permissions
being a bit tricky, there is follow-up work to be done.
What is done in this commit is the hash modifications. At the fetch
layer, executable bits inside packages are ignored. In the hash
computation layer, executable bit is implemented for POSIX but not yet
for Windows. This means that the hash will not break again in the future
for packages that do not have any executable files, but it will break
for packages that do.
This is a hash-breaking change.
Closes#14308
Usage of `catch unreachable` in build scripts is completely harmless
because build scripts are always run in Debug mode, however, it sets a
poor example for beginners to learn from.
These declarations are now aliases of their new APIs and marked as
deprecated via doc comments:
* std.build.Builder
* std.build
* std.Build.LibExeObjStep
This is a breaking change that makes the API for creating build
artifacts no longer have any period of time where the target and
optimization mode are not set.
* introduce the concept of maps to user input options, but don't
implement it for command line arg parsing yet.
* remove setPreferredReleaseMode and standardReleaseOptions in favor of
standardOptimizeOption which has a future-proof options parameter.
These functions are currently footgunny when working with pointers to
arrays and slices. They just return the stated length of the array/slice
without iterating and looking for the first sentinel, even if the
array/slice is a sentinel terminated type.
From looking at the quite small list of places in the standard
library/compiler that this change breaks existing code, the new code
looks to be more readable in all cases.
The usage of std.mem.span/len was totally unneeded in most of the cases
affected by this breaking change.
We could remove these functions entirely in favor of other existing
functions in std.mem such as std.mem.sliceTo(), but that would be a
somewhat nasty breaking change as std.mem.span() is very widely used for
converting sentinel terminated pointers to slices. It is however not at
all widely used for anything else.
Therefore I think it is better to break these few non-standard and
potentially incorrect usages of these functions now and at some later
time, if deemed worthwhile, finally remove these functions.
If we wait for at least a full release cycle so that everyone adapts to
this change first, updating for the removal could be a simple find and
replace without needing to worry about the semantics.
