Do we want GCC support back for 5.9? https://lkml.kernel.org/r/20200618093118.247375-1-elver@google.com I was hoping it could go into 5.9, because it makes a big difference in terms of usability as it provides more compiler choice. The only significant change for GCC support is the addition of the checking of (CC_IS_GCC && (....)). Thanks, -- Marco ^ permalink raw reply [flat|nested] 10+ messages in thread
