This "feature" of gcc/clang means to treat this as a positional
link object, but using the library search directories as a prefix.
We solve this problem in the CLI layer, using a separate map for
the data since it is an uncommon case.
Closes#10851
On Windows, `argv` is not populated by start code, and instead left as undefined. This is problematic, and can lead to incorrect programs compiling, but panicking when trying to access `argv`. This change causes these programs to produce a compile error on Windows instead, which is far preferable to a runtime panic.
* update number of type abbrevs to match Elf linker
* update `DebugSymbols` to write symbol and string tables
at the end to match the `MachO` linker
* TODO: update segment vm addresses when growing segments in
the binary
* TODO: store DWARF relocations in linker's interned arena
Previously, `suffix` was copied to `output_buffer` at position
`max_end`, thereby writing into reserved space after `max_end`.
This only worked because `suffix` was not larger than
`bytes_needed_for_esc_codes_at_end` (otherwise there'd be a potential
buffer overrun) and no escape codes at end are actually written.
Since 2d5b2bf1c986d037ef965bf8c9b4d8dfd5967478, escape codes are no
longer written to the end of the buffer. They are now written
exclusively to the front of the buffer.
This allows removing `bytes_needed_for_esc_codes_at_end` and
simplifying the suffix printing logic.
This also fixes the bug that the ellipse suffix was not printed in
Windows terminals because `end.* > max_end` was never true.
In #10859 I moved the `test_node.end()` call after everything else has
been logged. Now the `test_fn.name` is printed by `Progress` itself,
making the additional log obsolete.
The information whether a register is allocated to an instruction is
already encoded in the free_registers "bitmap". Duplicating that
information in the registers map is unnecessary and may lead to
performance degradations.
Implements a cross-platform metadata API, aiming to reduce unnecessary Unix-dependence of the `std.fs` api. Presently, all OSes beside Windows are treated as Unix; this is likely the best way to treat things by default, instead of explicitly listing each Unix-like OS.
Platform-specific operations are not provided by `File.Metadata`, and instead are to be accessed from `File.Metadata.inner`.
Adds:
- File.setPermissions() : Sets permission of a file according to a `Permissions` struct (not available on WASI)
- File.Permissions : A cross-platform representation of file permissions
- Permissions.readOnly() : Returns whether the file is read-only
- Permissions.setReadOnly() : Sets whether the file is read-only
- Permissions.unixSet() : Sets permissions for a class (UNIX-only)
- Permissions.unixGet() : Checks a permission for a class (UNIX-only)
- Permissions.unixNew() : Returns a new Permissions struct to represent the passed mode (UNIX-only)
- File.Metadata : A cross-platform representation of file metadata
- Metadata.size() : Returns the size of a file
- Metadata.permissions() : Returns a `Permissions` struct, representing permissions on the file
- Metadata.kind() : Returns the `Kind` of the file
- Metadata.accessed() : Returns the time the file was last accessed
- Metadata.modified() : Returns the time the file was last modified
- Metadata.created() : Returns the time the file was created (this is an optional, as the underlying filesystem, or OS may not support this)
Methods of `File.Metadata` are also available for the below, so I won't repeat myself
The below may be used for platform-specific functionality
- File.MetadataUnix : The internal implementation of `File.Metadata` on Unices
- File.MetadataLinux : The internal implementation of `File.Metadata` on Linux
- File.MetadataWindows : The implementation of `File.Metadata` on Windows
Previously the progress displayed the first item as [0/x]. This was
misleading when x is the number of items. The first item should be
displayed as [1/x]
