  "message": "[X86] Fix inline asm modifier printing across dialects (#204558)\n\nX86AsmPrinter handles several inline asm operand modifiers differently\ndepending on whether the asm block uses AT\u0026T or Intel syntax.\n\nFor `%a` and `%A`, the scalar/register operand path used AT\u0026T\npunctuation unconditionally. In Intel-dialect inline asm this could\nprint invalid forms such as `(rdi)` for an address operand or `*rdi` for\nan indirect call operand.\n\nFor `%P`, `PrintAsmMemoryOperand` passed `\"disp-only\"` to both the Intel\nand AT\u0026T memory printers, but only the Intel path honored it for\nglobal/symbol displacements with a base register. The AT\u0026T path could\ntherefore print `g(%rdi)` even though `%P` requested displacement-only\noutput.\n\nMake the affected X86 asm-printer paths dialect-aware/consistent:\n- print Intel `%a` register operands as `[reg]`\n- print Intel `%A` register operands without AT\u0026T `*`\n- make AT\u0026T `%P` honor `\"disp-only\"` for global/symbol displacements,\nmatching the existing Intel behavior\n\nFound via @jlebar\u0027s X86 LLVM bug-hunt / FuzzX effort.\n\ncc @jlebar\n\nCo-authored-by: Ayush Rai \u003cyour-email@amd.com\u003e",
