bors db2f9759f4 Auto merge of #122671 - Mark-Simulacrum:const-panic-msg, r=Nilstrieb ... Codegen const panic messages as function calls This skips emitting extra arguments at every callsite (of which there can be many). For a librustc_driver build with overflow checks enabled, this cuts 0.7MB from the resulting shared library (see [perf]). A sample improvement from nightly: ``` leaq str.0(%rip), %rdi leaq .Lalloc_d6aeb8e2aa19de39a7f0e861c998af13(%rip), %rdx movl $25, %esi callq *_ZN4core9panicking5panic17h17cabb89c5bcc999E@GOTPCREL(%rip) ``` to this PR: ``` leaq .Lalloc_d6aeb8e2aa19de39a7f0e861c998af13(%rip), %rdi callq *_RNvNtNtCsduqIKoij8JB_4core9panicking11panic_const23panic_const_div_by_zero@GOTPCREL(%rip) ``` [perf]: https://perf.rust-lang.org/compare.html?start=a7e4de13c1785819f4d61da41f6704ed69d5f203&end=64fbb4f0b2d621ff46d559d1e9f5ad89a8d7789b&stat=instructions:u		2024-03-29 00:24:01 +00:00
