--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
%c does not mean anything in loongarch.
The codes are not documented in the documentation for loonarch though but they
currently only documented in loongarch.cc:
'A' Print a _DB suffix if the memory model requires a release.
'b' Print the address of a memory operand, without offset.
'C' Print the integer branch condition for comparison OP.
'd' Print CONST_INT OP in decimal.
'F' Print the FPU branch condition for comparison OP.
'G' Print a DBAR insn if the memory model requires a release.
'H' Print address 52-61bit relocation associated with OP.
'h' Print the high-part relocation associated with OP.
'i' Print i if the operand is not a register.
'L' Print the low-part relocation associated with OP.
'm' Print one less than CONST_INT OP in decimal.
'N' Print the inverse of the integer branch condition for comparison OP.
'r' Print address 12-31bit relocation associated with OP.
'R' Print address 32-51bit relocation associated with OP.
'T' Print 'f' for (eq:CC ...), 't' for (ne:CC ...),
'z' for (eq:?I ...), 'n' for (ne:?I ...).
't' Like 'T', but with the EQ/NE cases reversed
'V' Print exact log2 of CONST_INT OP element 0 of a replicated
CONST_VECTOR in decimal.
'W' Print the inverse of the FPU branch condition for comparison OP.
'X' Print CONST_INT OP in hexadecimal format.
'x' Print the low 16 bits of CONST_INT OP in hexadecimal format.
'Y' Print loongarch_fp_conditions[INTVAL (OP)]
'y' Print exact log2 of CONST_INT OP in decimal.
'Z' Print OP and a comma for 8CC, otherwise print nothing.
'z' Print $0 if OP is zero, otherwise print OP normally. */
