[GitHub] [incubator-nuttx] yamt opened a new pull request #1342: sim: Sync Linux CMODULEFLAGS with macOS

yamt opened a new pull request #1342:
URL: https://github.com/apache/incubator-nuttx/pull/1342


   ## Summary
   Namely, always use -mcmodel=large.
   
   NuttX modules are loaded into the NuttX heap, which can be out of
   range for 32-bit relocations generated with -mcmodel=small.
   
   A possible alternative would be to use MAP_32BIT to allocate sim heap.
   But I prefer this approach because it's very convenient for me to
   be able to share modules between Linux and macOS sim.
   
   ## Impact
   Linux sim
   
   ## Testing
   manually tested with my local app.

   @liuguo09 
   oops. thank you for notification.
   
   i think it should be conditional with CONFIG_HOST_X86_64 && !CONFIG_SIM_M32.
   or, probably CONFIG_LIBC_ARCH_ELF_64BIT.
   
   hopefully i can submit a patch tomorrow.
