Description Denis Volkov 2020-07-30 11:04:59 UTC 
Description of problem:
Currently the latest version of gcc available for RHEL8 is gcc 9.2.1 (https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/developing_c_and_cpp_applications_in_rhel_8/gcc-toolset-9_toolsets)
At the same time RHEL7 provides gcc 9.3.1 in Developers Toolset 9.1 (https://access.redhat.com/documentation/en-us/red_hat_developer_toolset/9/html/9.1_release_notes/dts9.1_release#Changes_in_DTS)

RHEL8 should provide gcc 9.3 to at least be not behind RHEL7

Comment 6 Jeff Law 2020-08-17 16:11:39 UTC 
Unfortunately we would need a clear justification for updating the compiler.  The most recent reply from Siemens says "It doesn't make sense to use a faulty tool" -- that is not enough to justify an update, particulary at this stage in DTS 9's lifecycle.

We would need to know specifically what Siemens thinks is faulty.  ie, a testcase that is mis-compiled or which gives a incorrect diagnostic that is critical to Siemens so that we could fully evaluate the request.

User tells they would like 9.3.1 to match https://vfxplatform.com/ specification.

Otherwise, while not experiencing any specific issue, there is

Comment 9 Jeff Law 2020-08-26 15:58:41 UTC 
Paulo, the standard cycle for DTS is a .0 major release in the fall and a .1 bugfix release in the spring.   Further updates beyond those are restricted to major security issues or mission critical customer/partner bugfixes.  Neither of the two justifications in c#7 would be considered sufficient by engineering or product management to issue an additional DTS release.

The next planned DTS release is DTS 10 which will include gcc-10.x and is due out this fall.
