LeRoyce Pearson 733f1c25bd Fix compile errors in stage2 2020-04-02 23:39:25 -06:00
LeRoyce Pearson ea6525797d Use `flock` instead of `fcntl` to lock files 
`flock` locks based on the file handle, instead of the process id.
This brings the file locking on unix based systems closer to file
locking on Windows.

zig cc: fix ambiguity with -MT 
In an MSVC context, `-MT` means
"Use static run-time"
and it is a flag with no parameter.

On POSIX it means
"Specify name of main file output in depfile"
and it is "joined or separate".

The former was interfering with the latter. Now, the MT flag is required
to be specified with a `/` to disambiguate: `/MT`.

Timon Kruiper b5526d0b3b Fix multiplication overflow in `hash_const_val` 
In some cases the compiler was actually emitting an 64 bit signed
multiplication, instead of a 32 bit unsigned one.

slight modification of the semantics of std.os.getenvW 
Now, this function first attempts a case-sensitive lookup.
If no match is found, and `key` is ASCII, then it attempts a
second case-insensitive lookup.

It is not planned to support full Unicode case-insensitivity
on Windows, and in fact relying on non-ASCII case-insensitive
environment variables is fundamentally problematic.

Michael Dusan 212e2354b8 stage1: make C++ switch fallthrough an error 
Make fallthrough an error when compiler supports it. This requires a new
macro that is defined with such compilers to be used as a statement, at
all fallthrough sites:

    switch (...) {
        case 0:
            ...
            ZIG_FALLTHROUGH;
        case 1:
            ...
            break;
        default:
            ...
            break;
    }

If we ever move to C++17 as minimal requirement, then the macro can be
replaced with `[[fallthrough]];` at statement sites.

Timon Kruiper d33766e6c7 Make sure that ZigTypeVector and ZigTypeArray have the same memory layout 
Throughout the stage1 code it is assumed that these have the same layout,
but that was not the case. This caused an issue on 32-bit hardware.

(breaking) std.Buffer => std.ArrayListSentineled(u8, 0) 
This new name (and the fact that it is a function returning a type) will
make it more clear which use cases are better suited for ArrayList and
which are better suited for ArrayListSentineled.

Also for consistency with ArrayList,
 * `append` => `appendSlice`
 * `appendByte` => `append`

Thanks daurnimator for pointing out the confusion of std.Buffer.
