whitequark c8c3c7af87 Use [[maybe_unused]] instead of YS_ATTRIBUTE(unused). 
[[maybe_unused]] is available since C++17, so this commit adds
a polyfill YS_MAYBE_UNUSED. Once we require C++17 we can drop it.

whitequark 118e4caa37 Remove YS_ATTRIBUTE(unused) where present just for log_assert()/log_debug(). 2020-06-19 15:48:58 +00:00
whitequark 21692c4a2e Use (and ignore) the expression provided to log_debug in NDEBUG builds. 2020-06-19 15:48:58 +00:00
whitequark 2ffdb74fb1 Use (and ignore) the expression provided to log_assert in NDEBUG builds. 
This avoids warnings in NDEBUG builds emitted when a variable is only
used in log_assert, but is always defined.

Merge pull request #2175 from Xiretza/missing-noreturn 
Add missing [[noreturn]] to log_file_error()
 2020-06-19 15:46:54 +00:00
Xiretza 817411044a
Add missing [[noreturn]] to log_file_error() 
Previously this was tagged only with YS_ATTRIBUTE(noreturn), but not
YS_NORETURN, so it got lost in #2173, resulting in warnings in
frontends/ast/simplify.cc:

frontends/ast/simplify.cc:267:1: warning: function declared 'noreturn' should not return [-Winvalid-noreturn]
}
^
frontends/ast/simplify.cc:379:1: warning: function declared 'noreturn' should not return [-Winvalid-noreturn]

Merge pull request #2171 from whitequark/cxxrtl-accessors 
cxxrtl: add .get() and .set() accessors on value<> and wire<>
 2020-06-19 03:52:29 +00:00
whitequark 962a2f3bff cxxrtl: add .get() and .set() accessors on value<> and wire<>. 
For several reasons:
  * They're more convenient than accessing .data.
  * They accommodate variably-sized types like size_t transparently.
  * They statically ensure that no out of range conversions happen.

For now these are only provided for unsigned integers, but eventually
they should be provided for signed integers too. (Annoyingly this
affects conversions to/from `char` at the moment.)

Fixes #2127.

whitequark 7137f99658 kernel: guard include of signal.h more precisely. 
Upgrading to WASI SDK 11.0 caused the WASM build to fail because WASM
does not have signals. (Arguably Yosys was broken even before, it was
just broken silently.)

 2020-06-13 04:17:49 +00:00
whitequark 107911dbec cxxrtl: always inline internal cells and slice/concat operations. 
This can result in massive reduction in runtime, up to 50% depending
on workload. Currently people are using `-mllvm -inline-threshold=`
as a workaround (with clang++), but this solution is more portable.

whitequark 6cf02ed94f cxxrtl: fix rzext(). 
This was a correctness issue, but one of the consequences is that it
resulted in jumps in generated machine code where there should have
been none. As a side effect of fixing the bug, Minerva SoC became 10%
faster.
