bors bfcde309e7 auto merge of #15876 : brson/rust/failfat, r=pcwalton ... Adds a new runtime unwinding function that encapsulates the printing of the words "explicit failure" when `fail!()` is called w/o arguments. The before/after optimized assembly: ``` leaq "str\"str\"(1412)"(%rip), %rax movq %rax, 24(%rsp) movq $16, 32(%rsp) leaq "str\"str\"(1413)"(%rip), %rax movq %rax, 8(%rsp) movq $19, 16(%rsp) leaq 24(%rsp), %rdi leaq 8(%rsp), %rsi movl $11, %edx callq _ZN6unwind12begin_unwind21h15836560661922107792E ``` ``` leaq "str\"str\"(1369)"(%rip), %rax movq %rax, 8(%rsp) movq $19, 16(%rsp) leaq 8(%rsp), %rdi movl $11, %esi callq _ZN6unwind31begin_unwind_no_time_to_explain20hd1c720cdde6a116480dE@PLT ``` Before/after filesizes: rwxrwxr-x 1 brian brian 21479503 Jul 20 22:09 stage2-old/lib/librustc-4e7c5e5c.so rwxrwxr-x 1 brian brian 21475415 Jul 20 22:30 x86_64-unknown-linux-gnu/stage2/lib/librustc-4e7c5e5c.so This is the lowest-hanging fruit in the fail-bloat wars. Further fixes are going to require harder tradeoffs. r? @pcwalton		2014-07-22 10:46:16 +00:00
