    "content": "This patch changes the format used to print fixed-point constants from\nhex to decimal. For instance a negative \"short fract\" fixed-point\nconstant may be represented as a signed HOST_WIDE_INT from -1 to -128,\nwhich would currently be printed as e.g. 0xfff....ffxx, resulting in a\n\"bignum truncated to fit\" warning from the assembler. This trouble is\navoided if we just print using integers instead, similarly to the way\nsigned character-constants are emitted elsewhere in the compiler.\n\nTested along with the rest of the patch series. OK to apply?\n\nJulian\n\nChangeLog\n\n    * final.c (output_addr_const): Print fixed-point constants as\n    decimal not hex (avoiding an assembler overflow warning for\n    negative byte constants).",
