It does not really fit with the rest so I'll add this as a top post for the armv7 context:
Only main [so: 15] has armv7 lang/gcc14* build failures on teh oficial builders. Seems odd if it is just lang/gcc1[45]* 's problem. Official 14.1R builder success logs include: https://pkg-status.freebsd.org/ampere3/data/141releng-armv7-default/a66c1b68c862/logs/gcc14-14.2.0_3.log ---Begin OPTIONS List--- ===> The following configuration options are available for gcc14-14.2.0_3: GRAPHITE=off: Support for Graphite loop optimizations ====> Options available for the radio BOOTSTRAP: you can only select none or one of them LTO_BOOTSTRAP=off: Build using a full LTO bootstrap STANDARD_BOOTSTRAP=on: Build using a full bootstrap without LTO ===> Use 'make config' to modify these settings ---End OPTIONS List--- https://pkg-status.freebsd.org/ampere3/data/141releng-armv7-default/a66c1b68c862/logs/gcc14-devel-14.2.1.s20250308,1.log ---Begin OPTIONS List--- ===> The following configuration options are available for gcc14-devel-14.2.1.s20250308,1: GRAPHITE=off: Support for Graphite loop optimizations ====> Options available for the single BOOTSTRAP: you have to select exactly one of them LTO_BOOTSTRAP=off: Build using a full LTO bootstrap STANDARD_BOOTSTRAP=on: Build using a full bootstrap without LTO ===> Use 'make config' to modify these settings ---End OPTIONS List--- Note: armv7 has not had much build time in 2025-Apr so far, thus the lack of 14.2R examples.
