[PATCH-for-10.1 0/5] exec: Remove TARGET_LONG_SIZE definition

[PATCH-for-10.1 0/5] exec: Remove TARGET_LONG_SIZE definition

[Philippe Mathieu-Daudé]

TARGET_LONG_SIZE is only used in 1 source file
and 1 header. Remove it to be able to focus on
making TARGET_LONG_BITS target agnostic.

Philippe Mathieu-Daudé (5):
  target/i386: Use explicit little-endian LD/ST API
  gdbstub: Remove ldtul_be_p() and ldtul_le_p() macros
  target/ppc/gdbstub: Replace TARGET_LONG_SIZE -> sizeof(target_ulong)
  user/tswap: Replace TARGET_LONG_SIZE -> TARGET_LONG_BITS
  exec/target_long: Remove TARGET_LONG_SIZE definition

[PATCH-for-10.1 1/5] target/i386: Use explicit little-endian LD/ST API

[Philippe Mathieu-Daudé]

The x86 architecture uses little endianness. Directly use
the little-endian LD/ST API.

Mechanical change using:

  $ end=le; \
    for acc in uw w l q tul; do \
      sed -i -e "s/ld${acc}_p(/ld${acc}_${end}_p(/" \
             -e "s/st${acc}_p(/st${acc}_${end}_p(/" \
        $(git grep -wlE '(ld|st)t?u?[wlq]_p' target/i386/); \
    done

[PATCH-for-10.1 2/5] gdbstub: Remove ldtul_be_p() and ldtul_le_p() macros

[Philippe Mathieu-Daudé]

Last uses of ldtul_be_p() were removed in commit 78920b4ff2b
("target/sparc: Use explicit big-endian LD/ST API"), and of
ldtul_le_p() in 39631d57d7c ("target/riscv: Use explicit
little-endian LD/ST API"). Remove these legacy macros.

I'm guessing these are commits in your tree because I can't see them in
origin.

Oops. I'll respin altogether as a single series.

[PATCH-for-10.1 3/5] target/ppc/gdbstub: Replace TARGET_LONG_SIZE -> sizeof(target_ulong)

[Philippe Mathieu-Daudé]

TARGET_LONG_SIZE is equivalent of sizeof(target_ulong).
Since this is the single use of TARGET_LONG_SIZE in a
source file, use the equivalent form to be able to remove
the definition in a pair of commits.

[PATCH-for-10.1 4/5] user/tswap: Replace TARGET_LONG_SIZE -> TARGET_LONG_BITS

[Philippe Mathieu-Daudé]

Having in "exec/target_long.h" this definition:

  #define TARGET_LONG_SIZE (TARGET_LONG_BITS / 8)

It is safe to check TARGET_LONG_BITS == 32 instead
of the equivalent TARGET_LONG_SIZE == 4 expression.

This removes the last use of TARGET_LONG_SIZE outside
of "exec/target_long.h".

[PATCH-for-10.1 5/5] exec/target_long: Remove TARGET_LONG_SIZE definition

[Philippe Mathieu-Daudé]

Directly use TARGET_LONG_BITS, so we don't need
the TARGET_LONG_SIZE definition at all.
