Re: Merging calls to `abort'

But it seems to me that the practice of using abort() as it is now used

tradeoffs were different.  We can afford to tell the user more.

In addition, crossjumping calls to abort does more than just save space; it also saves time, because space *is* time on modern processors, where every bit of icache counts.

I don't see any reason for GCC to treat "abort" specially. It should at least treat all "noreturn" functions equivalently. But, beyond that, I'm a user who would rather than crossjumping be run on calls to "abort". I use "abort" only when I've already issued a useful diagnostic, and want to dump core. Otherwise, I use "assert", or an exception. So, I would not support this change.
