However, this reduces +the debuginfo coverage for variable locations, especially in inline +functions. VTA is certainly not perfect either in those cases, but it +is much better than without. With compiler versions that have fixed the +codegen bugs, we would prefer to have the better details for SystemTap, +and surely other debuginfo consumers like perf will benefit as well. + +This patch simply makes CONFIG_DEBUG_INFO_VTA an option. I considered +Frank and Linus's discussion of a cc-option-like -fcompare-debug test, +but I'm convinced that a narrow test of an arch-specific codegen issue +is not really useful. GCC has their own regression tests for this, so +I'd suggest GCC_COMPARE_DEBUG=-fvar-tracking-assignments-toggle is more +useful for kernel developers to test confidence. + +In fact, I ran into a couple more issues when testing for this patch[1], +although neither of those had any codegen impact. + [1] https://bugzilla.redhat.com/show_bug.cgi?id=1140872 + +With gcc-4.9.2-1.fc22, I can now build v3.18-rc5 with Fedora's i686 and +x86_64 configs, and this is completely clean with GCC_COMPARE_DEBUG. + +Cc: Frank Ch.
