Issue #20107 has been updated by kddnewton (Kevin Newton). Is that something we can address within Ruby or is it entirely outside of our control? @hsbt do you want to remove the old CI tasks or should I? ---------------------------------------- Misc #20107: Update required Oracle Solaris Studio version to 12.5 https://bugs.ruby-lang.org/issues/20107#change-106034 * Author: kddnewton (Kevin Newton) * Status: Open * Priority: Normal * Assignee: ngoto (Naohisa Goto) ---------------------------------------- Per https://www.oracle.com/us/assets/lifetime-support-hardware-301321.pdf and https://www.oracle.com/a/ocom/docs/support/advanced-customer-support/solaris..., 12.2, 12.3, and 12.4 are all end-of-life for "extended support". We should drop these old compilers from our support suite for Ruby 3.4.0 so that we can use more of C99. Specifically, in conjunction with bumping to Visual Studio 2015, I believe this means we can now rely on `stdbool.h`, the `restrict` keyword, `va_copy`, `snprintf`, and the `%zu` printf specifier all functioning as expected. -- https://bugs.ruby-lang.org/
