* New/better macro pragmas, make some experimental
fix#15920, close#18212, close#14781, close#6696,
close https://github.com/nim-lang/RFCs/issues/220
Variable macro pragmas have been changed to
only take a unary section node.
They can now also be applied in sections with multiple variables,
as well as `const` sections. They also accept arguments.
Templates now support macro pragmas, mirroring other routine types.
Type and variable macro pragmas have been made experimental.
Symbols without parentheses instatiating nullary macros or templates
has also been documented in the experimental manual.
A check for a redefinition error based on the left hand side of variable
definitions when using variable macro pragmas was disabled.
This nerfs `byaddr` specifically, however this has been documented as
a consequence of the experimental features `byaddr` uses.
Given how simple these changes are I'm worried if I'm missing something.
* accomodate compiler boot
* allow weird pragmas
* add test for #10994
* remove some control flow, try remove some logic
Instead of rejecting type expressions based on node kind,
evaluate the expression as a type.
This is already the behavior for call results, and it has its own error
for non-types, which is the same error you would normally get
with 2 words swapped.
* deprecate unsafeAddr; extend addr
addr is now available for all addressable locations, unsafeAddr is deprecated and become an alias for addr
* follow @Vindaar's advice
* change the signature of addr
* unsafeAddr => addr (stdlib)
* Update changelog.md
* unsafeAddr => addr (tests)
* Revert "unsafeAddr => addr (stdlib)"
This reverts commit ab83c99c50.
* doc changes; thanks to @konsumlamm

* Use openarray of bytes in md5
* fix CI
* cleanup
* use noSideEffect for bootstrapping
* fix CI again
* actually fix CI by checking if it works
* this is getting ridiculous
* put old md5 version in compiler, remove vmop
* Parameters now can constrain static in type definitions
resolved regression with generic procedures
* Update compiler/sigmatch.nim

* nimRawSetjmp: support Windows
Using `_setjmp()` directly is required to avoid some rare (but very
annoying) exception-related stack corruption leading to segfaults on
Windows, with Mingw-w64 and SEH.
More details: https://github.com/status-im/nimbus-eth2/issues/3121
Also add "nimBuiltinSetjmp" - mostly for benchmarking.
* fix for Apple's Clang++
When creating heterogenous slices of distinct types, the compiler does
not initialize the internal type's `size` before accessing it.
This then leads to this crash message:
```
compiler/int128.nim(594, 11) `false` masking only implemented for 1, 2, 4 and 8 bytes [AssertionError]
```
This patch initializes the `size` properly, fixing the problem.
