Thanks, Richard. I will take a look for the bootstrap ICE. Running one extra
local pure-const should be cheap enough and dropping large regions of EH code
seems like a win.
Concering the inline decision difference, perhaps you can have more insight. I
typically use tramp3d as a black box to test heuristic changes - it is almost
impossible for me to figure out why inlining decisions went wrong on this beast
;))
Why exactly does chkp pass can not run as part of early opts?
