[Tinycc-devel] [PATCH 0/9] Improve ARM inline assembler

From: Danny Milosavljevic
Subject: [Tinycc-devel] [PATCH 0/9] Improve ARM inline assembler
Date: Mon, 28 Dec 2020 02:44:04 +0100

This patchset improves the ARM inline assembler I posted earlier.

(Please apply it on top of the patchset I posted earlier--it does
not replace it)

First, I add support for the barrel shifter--supporting specifying both
modifiers for the old ARM instructions and also the new ARM shift

I add ROR support for sxtb, sxth, uxtb, uxth.

I add some warnings and errors for some cases that are not supported by
ARM hardware.

Danny Milosavljevic (9):
  arm-asm: Add lsl, lsr, asr, ror, rrx
  arm-asm: For data processing instructions, support shifts and
  arm-asm: Support rotation for sxtb, sxth, uxtb, uxth
  arm-asm: Warn if regset registers are not specified in ascending order
  arm-asm: Add error case in asm_multiplication_opcode
  arm-asm: Raise an error if asm_binary_opcode is used with PC as
  arm-asm: Print a warning if asm_binary_opcode is used with SP as
  arm-asm: Raise error if more than two operands are specified on mov,
    mvn, cmp, cmn, tst, teq
  arm-asm: Raise error if asm_data_processing_opcode and
    asm_shift_opcode try to use PC for register-controlled shifts
