The primary supported (and best tested) processor families are 64- and 32-bit ARM<!-- arch64 and arm-->, 64- and 32-bit [[x86 64]] and [[x86]]<!-- aka e.g. i686 --> and 64-bit [[PowerPC]] and [[SPARC]].<ref>{{Cite web |date=2022-10-26 |title=GCC 12 Release Criteria |url=https://gcc.gnu.org/gcc-12/criteria.html |access-date=2023-01-27 |website=gcc.gnu.org |archive-date=January 27, 2023 |archive-url=https://web.archive.org/web/20230127213916/https://gcc.gnu.org/gcc-12/criteria.html |url-status=live }}</ref> <!-- Notably absent from primary list is e.g. RISC-V and MIPS has been moved to secondary, but the latter has been tested for a long time, and both may actually work well, not sure. Nor sure what to read into OS support, known to work for e.g. Windows (i686-pc-cygwin, i686-mingw32 also 64-bit?):

https://gcc.gnu.org/gcc-12/criteria.html

The primary platforms are:
aarch64-none-linux-gnu
arm-linux-gnueabi
i586-unknown-freebsd
i686-pc-linux-gnu
powerpc64-unknown-linux-gnu
powerpc64le-unknown-linux-gnu
sparc-sun-solaris2.11
x86_64-pc-linux-gnu

The secondary platforms are:
aarch64-elf
i686-apple-darwin
i686-pc-cygwin
i686-mingw32
powerpc-ibm-aix7.1.0.0
s390x-linux-gnu

The [[GNU Compiler for Java|GCJ]] Java compiler can target either a native machine language architecture or the [[Java virtual machine]]'s [[Java bytecode]].<ref>{{cite web|url=https://gcc.gnu.org/java/|title=The GNU Compiler for the Java Programming Language|access-date=2010-04-22|url-status=dead|archive-url=https://web.archive.org/web/20070509055923/http://gcc.gnu.org/java/|archive-date=May 9, 2007|df=mdy-all}}</ref> When [[retargetable compiler|retargeting]] GCC to a new platform, [[bootstrapping (compilers)|bootstrapping]] is often used. Motorola 68000, Zilog Z80, and other processors are also targeted in the GCC versions developed for various Texas Instruments, Hewlett Packard, Sharp, and Casio programmable graphing calculators.<ref>graphing calculators#programming</ref>
