2024-12-17Win32: Add coroutine for mswin on arm64Nobuyoshi Nakada
Notes: Merged: https://github.com/ruby/ruby/pull/12367
2024-12-17Fix coroutine implementaion on Windows-Arm64Lars Kanis
When setjmp/longjmp/exceptions are used on Windows it's necessary to store+restore additional information from the TEB. I didn't find any official documentation about the values to be saved, but found the corresponding boost/context implemenataion: https://github.com/boostorg/context/commit/abf8e04e23cf05a499594e674d1c90db39117662 This is similar to the special TIB handling on x86/x86_64 on Windows. Without this fix an exception in a fiber segfaults without any output: ruby -e "Fiber.new{ raise 'test' }.resume" Notes: Merged: https://github.com/ruby/ruby/pull/12363

2024-08-22Don't emit ELF notes on non-ELF platformsKJ Tsanaktsidis
These apparently break compilation on old MacOS toolchains, because the MachO section name is capped to 16 chars (although, on my MacOS, at least, the section name just gets truncated). Nevertheless, these serve no purpose on non-ELF platforms (they're part of the LSB Linux ABI). [Bug #20677] Notes: Merged: https://github.com/ruby/ruby/pull/11405
2024-08-22Fix typo in ELF note generationKJ Tsanaktsidis
This wasn't looking at the right macro name for pac-ret support, so if Ruby was compiled with pac-ret but NOT BTI, then the ELF note would not be emitted. Notes: Merged: https://github.com/ruby/ruby/pull/11405
2024-07-07Revert autoconf macros defining RUBY_AARCH64_{BTI|PAC}_ENABLEDKJ Tsanaktsidis
This partially reverts https://github.com/ruby/ruby/pull/10944; now that we decided to pass CFLAGS to $(CC) when assembling .S files, we don't need these autoconf macros that capture the state of __ARM_FEATURE{PAC|BTI}_DEFAULT. [Bug #20601]
2024-06-11Extract hardening CFLAGS to a special $hardenflags variableKJ Tsanaktsidis
This changes the automatic detection of -fstack-protector, -D_FORTIFY_SOURCE, and -mbranch-protection to write to $hardenflags instead of $XCFLAGS. The definition of $cflags is changed to "$hardenflags $orig_cflags $optflags $debugflags $warnflags" to match. Furthermore, these flags are _prepended_ to $hardenflags, rather than appended. The implications of doing this are as follows: * If a CRuby builder specifies cflags="-mbranch-protection=foobar" at the ./configure script, and the configure script detects that -mbranch-protection=pac-ret is accepted, then GCC will be invoked as "gcc -mbranch-protection=pac-ret -mbranch-protection=foobar". Since the last flags take precedence, that means that user-supplied values of these flags in $cflags will take priority. * Likewise, if a CRuby builder explicitly specifies "hardenflags=-mbranch-protection=foobar", because we _prepend_ to $hardenflags in our autoconf script, we will still invoke GCC as "gcc -mbranch-protection=pac-ret -mbranch-protection=foobar". * If a CRuby builder specifies CFLAGS="..." at the configure line, automatic detection of hardening flags is ignored as before. * C extensions will _also_ be built with hardening flags now as well (this was not the case by default before because the detected flags went into $XCFLAGS). Additionally, as part of this work, I changed how the detection of PAC/BTI in Context.S works. Rather than appending the autodetected option to ASFLAGS, we simply compile a set of test programs with the actual CFLAGS in use to determine what PAC/BTI settings were actually chosen by the builder. Context.S is made aware of these choices through some custom macros. The result of this work is that: * Ruby will continue to choose some sensible defaults for hardening options for the C compiler * Distributors are able to specify CFLAGS that are consistent with their distribution and override these defaults * Context.S will react to whatever -mbranch-protection is actually in use, not what was autodetected * Extensions get built with hardening flags too.

2023-12-22coroutine/arm64: Skip saving/restoring x30 twice and use `autiasp`Yuta Saito
We don't need to save/restore x30 twice, and we can just use `ret`, which uses x30 as return address register instead of explicit `ret <reg>` instruction. This also allows us to use `autiasp` instead of `autia1716` and we can skip setting SP/LR to x16/x17. Also the size of register save area is shrunk by 16 bytes due to the removal of extra x30 save/restore.

2019-12-26decouple internal.h headers卜部昌平
Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies). Notes: Merged: https://github.com/ruby/ruby/pull/2711
