2020-04-13include what you use.卜部昌平
This reverts commit 443389effc37308ce1a3c3a840082a344fc6af56. This reverts commit d94960f22ec2de3a3855305cb51343806d2b46c7. Inclusion of header files must be explicit. Every file shall directly include what is necessary. https://github.com/include-what-you-use/include-what-you-use says: > When every file includes what it uses, then it is possible to edit any > file and remove unused headers, without fear of accidentally breaking > the upwards dependencies of that file. It also becomes easy to > automatically track and update dependencies in the source code. Though we don't use iwyu itself, the principle quoted above is a good thing that we can agree. Now that include guards were added to every and all of the headers inside of our project this changeset does not increase compile time, at least on my machine.

2020-04-13add #include guard hack卜部昌平
According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

2020-04-11Enable fastpath on invokesuper (#3021)Takashi Kokubun
Fastpath has not been used for invokesuper since it has set vm_call_super_method on every invocation. Because it seems to be blocked only by refinements, try enabling fastpath on invokesuper when cme is not for refinements. While this patch itself should be helpful for VM performance, a part of this patch's motivation is to unblock inlining invokesuper on JIT. $ benchmark-driver -v --rbenv 'before;after' benchmark/vm2_super.yml --repeat-count=4 before: ruby 2.8.0dev (2020-04-11T15:19:58Z master a01bda5949) [x86_64-linux] after: ruby 2.8.0dev (2020-04-12T02:00:08Z invokesuper-fastpath c171984ee3) [x86_64-linux] Calculating ------------------------------------- before after vm2_super 20.031M 32.860M i/s - 6.000M times in 0.299534s 0.182593s Comparison: vm2_super after: 32859885.2 i/s before: 20031097.3 i/s - 1.64x slower Notes: Merged-By: k0kubun <takashikkbn@gmail.com>

2020-04-11Don't require sub-word atomicsAndreas Schwab
On some architectures (like RISC-V) sub-word atomics are only available when linking against -latomic, but the configure script doesn't do that, causing the atomic checks to fail and the resulting ruby binary is non-functional. Ruby does not use sub-word atomic operations, rb_atomic_t is defined to unsigned int, so use unsigned int when checking for atomic operations. Notes: Merged: https://github.com/ruby/ruby/pull/3016

2020-04-10Turn class variable warnings into exceptionsJeremy Evans
This changes the following warnings: * warning: class variable access from toplevel * warning: class variable @foo of D is overtaken by C into RuntimeErrors. Handle defined?(@@foo) at toplevel by returning nil instead of raising an exception (the previous behavior warned before returning nil when defined? was used). Refactor the specs to avoid the warnings even in older versions. The specs were checking for the warnings, but the purpose of the related specs as evidenced from their description is to test for behavior, not for warnings.

2020-04-10ruby3_rstring_getmem: suppres warning卜部昌平
icc warns at this line. > include/ruby/3/core/rstring.h(126): warning #413: variable "retval" has an uninitialized const field > struct RString retval; > ^ This must not be a problem because uninitialized const field is not used at all. But the warnings are annoying. Let us suppress them. Notes: Merged: https://github.com/ruby/ruby/pull/3011
2020-04-10RUBY3_ASSUME: suppress warnings on icc卜部昌平
icc warns side effects for RUBY3_ASSUME like this: > ./include/ruby/3/value_type.h(202): warning #2261: __assume expression with side effects discarded > RUBY3_ASSUME(RB_FLONUM_P(obj)); > ^ Which is a false positive (RB_FLONUM_P has no side effect). It seems there is no way for us to tell icc that a functin is safe inside of __assume. Just suppress the warning instead. Notes: Merged: https://github.com/ruby/ruby/pull/3011
2020-04-10configure: suppress SunPro warning卜部昌平
To this date there is no way for Oracle developer Studio to suppress warnings about unreachable codes (12.6 manual says it implemented __builtin_unreachable "as a no-op to C++. It might be added to C.") There is no way but globally kill the warning. Notes: Merged: https://github.com/ruby/ruby/pull/3011
2020-04-10configure: suppress icc warnings卜部昌平
Every time a pointer to/from VALUE conversion happens, these two warnings are issued: - warning #1684: conversion from pointer to same-sized integral type (potential portability problem) - warning #2312: pointer cast involving 64-bit pointed-to type Thank you, but we are well aware of the "potential portability problem". Let us ignore them all. Notes: Merged: https://github.com/ruby/ruby/pull/3011
2020-04-10configure: always check for __builtin_unreachable卜部昌平
Non-gcc compilers tend to have this intrinsic these days (e.g. icc). Better check it regardless of $GCC. Notes: Merged: https://github.com/ruby/ruby/pull/3011
2020-04-10RUBY3_HAS_BUILTIN: fix __builtin_unreachable卜部昌平
