https://bugzilla.redhat.com/show_bug.cgi?id=1192742 Bug ID: 1192742 Summary: Fix DWARF for variable references Product: Fedora Version: rawhide Component: golang Assignee: vbatts(a)redhat.com Reporter: jan.kratochvil(a)redhat.com QA Contact: extras-qa(a)fedoraproject.org CC: admiller(a)redhat.com, golang(a)lists.fedoraproject.org, lemenkov(a)gmail.com, lsm5(a)redhat.com, renich(a)woralelandia.com, s(a)shk.io, vbatts(a)redhat.com Created attachment 991800 --> https://bugzilla.redhat.com/attachment.cgi?id=991800&action=edit A bit hacky fix Description of problem: https://sourceware.org/gdb/wiki/GoDebugging#golang_Wrong_DW_TAG_variable golang provides &name variable names and the DWARF interface uses one more pointer than in the source. Version-Release number of selected component (if applicable): golang-1.4.1-1.fc22.x86_64 How reproducible: Always. Steps to Reproduce: ------------------- package main func main () { var i int ip:=&i ipp:=&ip go func() { **ipp++ }() } ------------------- Actual results: (gdb) b 8 (gdb) r (gdb) p i No symbol "i" in current context. (gdb) p &i No symbol "i" in current context. (gdb) p '&i' Invalid character constant. (gdb) p ' &i' $1 = (int *) 0xc20800a080 (gdb) p *' &i' $2 = 0 (gdb) p ' &ip' $3 = (int **) 0xc20803a000 (gdb) p *' &ip' $4 = (int *) 0xc20800a080 (gdb) p **' &ip' $5 = 0 (gdb) p ' &ipp' $6 = (int ***) 0xc20803a008 (gdb) p *' &ipp' $7 = (int **) 0xc20803a000 (gdb) p **' &ipp' $8 = (int *) 0xc20800a080 (gdb) p ***' &ipp' $9 = 0 Expected results: (gdb) b 8 (gdb) r (gdb) p i $1 = (int &) @0xc20800a080: 0 (gdb) p ip $2 = (int *&) @0xc20803a000: 0xc20800a080 (gdb) p *ip $3 = 0 (gdb) p ipp $4 = (int **&) @0xc20803a008: 0xc20803a000 (gdb) p *ipp $5 = (int *) 0xc20800a080 (gdb) p **ipp $6 = 0 (gdb) whatis i type = int & (gdb) whatis ip type = int *& (gdb) whatis ipp type = int **& Additional info: But you said golang upstream is writing some new linker so maybe this hack is not much relevant for upstream. DW_AT_name of the reference types is IMO incorrect but I do not think it matters much for GDB; for 'ipp' with this patch there is: <fe78> DW_AT_name : &(***int) -- You are receiving this mail because: You are on the CC list for the bug.
