// In theory the compiler instantiates count,

// count and count. In practice, only

// count is emitted, thanks to constant folding.

// So in theory, each of the 3 instances of count yields a

// DW_TAG_GNU_template_parameter_pack DIE, but in practise, there is only one

// DW_TAG_GNU_template_parameter_pack as there is only count

// is emitted.

// { dg-final { scan-assembler-times "DIE \\(0x.*?\\) DW_TAG_GNU_template_parameter_pack" 1} }

// { dg-final { scan-assembler-times "DIE \\(0x.*?\\) DW_TAG_template_type_param" 3} }
