From 1d62835fdae38a8f9814d77c54d752c2cfd30de9 Mon Sep 17 00:00:00 2001 From: Stian Halseth Date: Thu, 08 Oct 2026 09:45:11 +0200 Subject: [PATCH] qprocessordetection.h: Detect 64-bit SPARC when building with GCC GCC defines __sparc64__ only for the BSD targets. On Linux and Solaris it defines __arch64__, so Q_PROCESSOR_SPARC_64 was never set in a GCC build there. Check for __arch64__ as well, which GCC and clang both define on every 64-bit SPARC target. This only changes qtdeclarative, whose sparc64 heap pointer encoding was never compiled in. The other users test Q_PROCESSOR_SPARC_V9 first. Pick-to: 6.12 6.8 Task-number: QTBUG-141832 Change-Id: I88321df6e8c255d9288a17521d4a52138651df3b Reviewed-by: John Paul Adrian Glaubitz Reviewed-by: Thiago Macieira --- diff --git a/src/corelib/global/qprocessordetection.h b/src/corelib/global/qprocessordetection.h index 7dbd38d..2ab321c 100644 --- a/src/corelib/global/qprocessordetection.h +++ b/src/corelib/global/qprocessordetection.h @@ -334,7 +334,7 @@ # if defined(__sparc_v9__) || defined(__sparcv9) # define Q_PROCESSOR_SPARC_V9 # endif -# if defined(__sparc64__) +# if defined(__sparc64__) || defined(__arch64__) # define Q_PROCESSOR_SPARC_64 # endif # define Q_BYTE_ORDER Q_BIG_ENDIAN
