Egy tökéletes világban

Egy tökéletes világban a házi kedvenced mancsai mindig tiszták, a gyerekeid, akiknek soha sincs elég idejük arra, hogy megtöröljék a lábukat, mielőtt beszaladnának a szobába, most száraz és tiszta cipővel fognak belépni. Persze a világ nem tökéletes - viszont elég rálépni a Clean Step Mat lábtö

Re: Suse Linux ( s390x-linux-gnu-gcc )

You already sent this email to the gcc-help list, please don't cross-post here as well, see https://gcc.gnu.org/lists.html#policies It is almost never appropriate to send to both lists, either you're asking for help using GCC or you're talking about development of GCC, not both. On 23 May 2018

PR80155: Code hoisting and register pressure

Hi, I am trying to work on PR80155, which exposes a problem with code hoisting and register pressure on a leading embedded benchmark for ARM cortex-m7, where code-hoisting causes an extra register spill. I have attached two test-cases which (hopefully) are representative of the original test-case.
