CodeView symbols have to be multiples of four bytes; add an alignment directive to write_data_symbol to ensure this.
Note that these can be zeroes, so we can rely on GAS to do this for us; it's only types that need f3, f2, f1 values. gcc/ * dwarf2codeview.cc (write_data_symbol): Add alignment directive. --- gcc/dwarf2codeview.cc | 2 ++ 1 file changed, 2 insertions(+) diff --git a/gcc/dwarf2codeview.cc b/gcc/dwarf2codeview.cc index 71049ccf878..5a33b439b14 100644 --- a/gcc/dwarf2codeview.cc +++ b/gcc/dwarf2codeview.cc @@ -958,6 +958,8 @@ write_data_symbol (codeview_symbol *s) ASM_OUTPUT_ASCII (asm_out_file, s->data_symbol.name, strlen (s->data_symbol.name) + 1); + ASM_OUTPUT_ALIGN (asm_out_file, 2); + targetm.asm_out.internal_label (asm_out_file, SYMBOL_END_LABEL, label_num); end: -- 2.44.2
