[PATCH v2 0/9] hw, ui, virtfs-proxy-helper: Reduce QEMU .data/.rodata/.b

From: Philippe Mathieu-Daudé
Subject: [PATCH v2 0/9] hw, ui, virtfs-proxy-helper: Reduce QEMU .data/.rodata/.bss footprint
Date: Thu, 5 Mar 2020 13:45:16 +0100

Since v1:
- merged 2 series
- reworked hw/usb/quirks
- added R-b/A-b tags

This series reduce the footprint of the QEMU binary:
.bss: 106KiB (moved to .heap)
.data: 1MiB
.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 (9):
  hw/audio/fmopl: Fix a typo twice
  hw/audio/fmopl: Move ENV_CURVE to .heap to save 32KiB of .bss
  hw/audio/intel-hda: Use memory region alias to reduce .rodata by
  hw/net/e1000: Add readops/writeops typedefs
  hw/net/e1000: Move macreg[] arrays to .rodata to save 1MiB of .data
  hw/usb/quirks: Use smaller types to reduce .rodata by 10KiB
  ui/curses: Make control_characters[] array const
  ui/curses: Move arrays to .heap to save 74KiB of .bss
  virtfs-proxy-helper: Make the helper_opts[] array const
