4dcd1e6059 start code: overwrite AT_RANDOM after we use it 2020-12-18 12:22:46 -07:00

013efaf139 std: introduce a thread-local CSPRNG for general use 
std.crypto.random

* cross platform, even freestanding
* can't fail. on initialization for some systems requires calling
  os.getrandom(), in which case there are rare but theoretically
  possible errors. The code panics in these cases, however the
  application may choose to override the default seed function and then
  handle the failure another way.
* thread-safe
* supports the full Random interface
* cryptographically secure
* no syscall required to initialize on Linux (AT_RANDOM)
* calls arc4random on systems that support it

`std.crypto.randomBytes` is removed in favor of `std.crypto.random.bytes`.

I moved some of the Random implementations into their own files in the
interest of organization.

stage2 no longer requires passing a RNG; instead it uses this API.

Closes #6704

ce65533985 std: Properly fix the TLS alignment problem 
ad05509 introduced a fix for the wrong problem, the logic to align the
start of main_thread_tls_buffer was already there but was flawed.

Fix it for good and avoid wasting too many bytes for alignment purposes.

ad05509930 std: align(16) main_thread_tls_buffer 
Before this change, thread local variables were landmines if LLVM
decided to optimize any writes to them using vector instructions.

stage2: print package path on --pkg-begin failure 
This makes it much easier for the user to figure out what has gone wrong
than dumping an error return trace.

135f4791e5 std: Don't hash undefined bits 
auto_hash must be extra careful when hashing integers whose bit size is
not a multiple of 8 as, when reinterpreted with mem.asBytes, may contain
undefined non-zero bits too.

8f1408578c update the CPU target features and models 
Rather than directly pasting the output from the
target-details-generator tool, we have to look at the diff line by line
and decide how to incorporate the changes.

The baseline abstraction is something that Zig provides.

The changes to x86 appear to be incorrect. After LLVM commit
3ad09fd03c51823aeb0bcbd7898aada33e9228d6 the CPU features are stored in
a different data layout in their tables, and so we need to update the
target details extraction tool to match.
