Hi, This patch adds a GCC MIPS command line option (-mxpa) to enable/disable support for the eXtended Physical Address (XPA) instructions within the assembler.
The ChangeLog and patch are shown below. Many thanks, Andrew * doc/invoke.texi: Document -mxpa and -mno-xpa MIPS command line options. * config/mips/mips.opt (mxpa): New option. * config/mips/mips.h (ASM_SPEC): Pass mxpa and mno-xpa to the assembler. diff --git a/gcc/config/mips/mips.h b/gcc/config/mips/mips.h index b25865b..91a33ef 100644 --- a/gcc/config/mips/mips.h +++ b/gcc/config/mips/mips.h @@ -1176,6 +1176,7 @@ struct mips_cpu_info { %{mmcu} %{mno-mcu} \ %{meva} %{mno-eva} \ %{mvirt} %{mno-virt} \ +%{mxpa} %{mno-xpa} \ %{msmartmips} %{mno-smartmips} \ %{mmt} %{mno-mt} \ %{mfix-rm7000} %{mno-fix-rm7000} \ diff --git a/gcc/config/mips/mips.opt b/gcc/config/mips/mips.opt index 6ee5398..c992cee 100644 --- a/gcc/config/mips/mips.opt +++ b/gcc/config/mips/mips.opt @@ -392,6 +392,10 @@ mvirt Target Report Var(TARGET_VIRT) Use Virtualization Application Specific instructions +mxpa +Target Report Var(TARGET_XPA) +Use eXtended Physical Address (XPA) instructions + mvr4130-align Target Report Mask(VR4130_ALIGN) Perform VR4130-specific alignment optimizations diff --git a/gcc/doc/invoke.texi b/gcc/doc/invoke.texi index ff43f26..22a66e8 100644 --- a/gcc/doc/invoke.texi +++ b/gcc/doc/invoke.texi @@ -781,6 +781,7 @@ Objective-C and Objective-C++ Dialects}. -mmcu -mmno-mcu @gol -meva -mno-eva @gol -mvirt -mno-virt @gol +-mxpa -mno-xpa @gol -mmicromips -mno-micromips @gol -mfpu=@var{fpu-type} @gol -msmartmips -mno-smartmips @gol @@ -17494,6 +17495,12 @@ Use (do not use) the MIPS Enhanced Virtual Addressing instructions. @opindex mno-virt Use (do not use) the MIPS Virtualization Application Specific instructions. +@item -mxpa +@itemx -mno-xpa +@opindex mxpa +@opindex mno-xpa +Use (do not use) the MIPS eXtended Physical Address (XPA) instructions. + @item -mlong64 @opindex mlong64 Force @code{long} types to be 64 bits wide.
