[Bug 1827175] [NEW] armv8l-unknown-linux-gnueabihf triplet from clang -dumpmachine on ARMv7l
Public bug reported: I'm working on a Tritium ARMv7 dev board (https://www.amazon.com/gp/product/B07D4L7GXZ). It has a Cortex-A7 (https://libre.computer/products/boards/all-h3-cc/). I'm testing native build of a package using Clang. GCC provides the following triplet: $ gcc -dumpmachine arm-linux-gnueabihf Clang provides the following triplet: $ clang -dumpmachine armv8l-unknown-linux-gnueabihf The Clang triplet is very unusual. I've never seen a compiler claim armv8l. ARM does not even have a hit for ARMv8l on their site (https://www.google.com/search?q="armv8l"+site%3Aarm.com). According to https://github.com/tsandmann/armv8l-toolchain-linux, it is an ARM A-53 toolchain. It looks like the mis-identification is causing some folks trouble, including me (https://stackoverflow.com/q/27121199/608639). Perhaps it would be a good idea if Clang reported something closer to the board it is running on. $ lsb_release -a No LSB modules are available.
