* varasm.c (default_asm_output_anchor): Prepend * to . symbol in
order to prevent it from being munged by the target.

Index: gcc/varasm.c

--- gcc/varasm.c (revision 121945) +++ gcc/varasm.c (working copy) @@ -6098,7 +6098,7 @@ default_asm_output_anchor (rtx symbol) { char buffer[100];

• sprintf (buffer, ". + " HOST_WIDE_INT_PRINT_DEC,

• sprintf (buffer, "*. + " HOST_WIDE_INT_PRINT_DEC, SYMBOL_REF_BLOCK_OFFSET (symbol)); ASM_OUTPUT_DEF (asm_out_file, XSTR (symbol, 0), buffer); }

Hmmm, that's weird. Why does ASM_OUTPUT_DEF pass the VALUE parameter to assemble_name? Worse, the version in c4x.h does not do this.

Given that ASM_OUTPUT_DEF works this way, and given that we are not going to change that now, I think this patch is obvious.
