[AArch64][llvm] Fix disassembly of ldt{add,set,clr} instructions using xzr/wzr (#152292)
The current disassembly of `ldt{add,set,clr}` instructions when using `xzr/wzr` is incorrect. The Armv9.6-A Memory Systems specification says: ``` For each of LDT{ADD|SET|CLR}{L}, there is the corresponding STT{ADD|SET|CLR}{L} alias, for the case where the register selected by the Rt field is XZR or WZR ``` and: ``` LDT{ADD|SET|CLR}{A}{L} is equivalent to LD{ADD|SET|CLR}{A}{L} except that: <..conditions..> ``` The Arm ARM specifies the preferred form of disassembly for these aliases: ``` STADD <Xs>, [<Xn|SP>] is equivalent to LDADD <Xs>, XZR, [<Xn|SP>] and is always the preferred disassembly. ``` (ref: DDI 0487L.b C6-2317) This means that `sttadd` is the preferred disassembly for `ldtadd w0, wzr, [x2]` when Rt is `xzr` or `wzr`. This change also aligns llvm disassembly with GNU binutils, as shown by the following examples: llvm before this change: ``` % cat test.s stadd w0, [sp] sttadd w0, [sp] ldadd w0, wzr, [sp] ldtadd w0, wzr, [sp] % llvm-mc-20 -triple aarch64 -mattr=+lse,+lsui test.s stadd w0, [sp] ldtadd w0, wzr, [sp] stadd w0, [sp] ldtadd w0, wzr, [sp] ``` llvm after this change: ``` % llvm-mc -triple aarch64 -mattr=+lse,+lsui test.s stadd w0, [sp] sttadd w0, [sp] stadd w0, [sp] sttadd w0, [sp] ``` GCC-15 test: ``` % gas test.s -march=armv8-a+lsui+lse -o test.o % objdump -dr test.o 0: b82003ff stadd w0, [sp] 4: 192007ff sttadd w0, [sp] 8: b82003ff stadd w0, [sp] c: 192007ff sttadd w0, [sp] ``` Many thanks to Ezra Sitorus and Alice Carlotti for reporting and confirming this issue.
