With this change the DWARF now has DW_TAG_template_type_param for types, not just for functions, like: <2><40d>: Abbrev Number: 6 (DW_TAG_structure_type) <40e> DW_AT_name : (indirect string, offset: 0x375): Generic<i32> <412> DW_AT_byte_size : 4 <413> DW_AT_alignment : 4 ... <3><41f>: Abbrev Number: 8 (DW_TAG_template_type_param) <420> DW_AT_type : <0x42a> <424> DW_AT_name : (indirect string, offset: 0xa65e): T Closes #9224 2018-11-29T23:52:16+00:00 Nikita Popov nikita.ppv@gmail.com 2018-11-29T22:05:23+00:00 urn:sha1:cbf748993f59682f60dfe620eafea24124f737fb If the Rust LLVM fork is used, enable the -mergefunc-use-aliases flag, which will create aliases for merged functions, rather than inserting a call from one to the other. A number of codegen tests needed to be adjusted, because functions that previously fell below the thunk limit are now being merged. Merging is prevented either using -C no-prepopulate-passes, or by making the functions non-identical. I expect that this is going to break something, somewhere, because it isn't able to deal with aliases properly, but we won't find out until we try :) This fixes #52651. 2018-11-29T20:04:09+00:00 Tom Tromey tom@tromey.com 2018-10-12T13:34:14+00:00 urn:sha1:fb204cb92f5da2cd0b630ee4b6be85b02404823e This changes debuginfo generation to add template parameters to generic types.
