Subject: [PATCH 0/6] hw,ui: Reduce QEMU .rodata/.bss footprint
Date: Wed,  4 Mar 2020 23:18:01 +0100	[thread overview]
Message-ID: <20200304221807.25212-1-philmd@redhat.com> (raw)

This series reduce the footprint of the QEMU binary:
.bss: 106KiB (moved to .heap)
.rodata: 4.34MiB
(sizes on x86_64 building with -Os)

The elf-dissector tool [1] [2] helped to notice the big array.

Philippe Mathieu-Daudé (6):
  hw/audio/fmopl: Fix a typo twice
  hw/audio/fmopl: Move ENV_CURVE to .heap to save 32KiB of .bss
  hw/usb/quirks: Use smaller types to reduce .rodata by 10KiB
  hw/audio/intel-hda: Use memory region alias to reduce .rodata by
    4.34MB
  ui/curses: Make control_characters[] array const
  ui/curses: Move arrays to .heap to save 74KiB of .bss
