2009-07-21do not use ONONAMEs for line number information,Russ Cox1-0/+1
just like ONAME etc. R=ken OCL=31964 CL=31964
2009-07-20avoid strncat in formatters.Russ Cox1-94/+55
the n argument to strncat is the maximum number of bytes to read from the src, not the total size of the destination. R=ken OCL=31871 CL=31875
2009-07-17baby step: const decls can refer to futureRuss Cox1-7/+17
consts in the same factored block const ( X = Y; Y = 2; ) R=ken OCL=31782 CL=31782
2009-07-17another step toward eliminating forward declarations.Russ Cox1-215/+137
introduce NodeList* type in compiler to replace OLIST. this clarifies where lists can and cannot occur. list append and concatenation are now cheap. the _r rules are gone from yacc. rev and unrev are gone. no more lists of lists. the representation of assignments is a bit clunkier. split into OAS (1=1) and OAS2 (2 or more on one side). delete dead chanrecv3 code. delay construction of func types. R=ken OCL=31745 CL=31762
2009-07-13step toward no function prototypes.Russ Cox1-16/+34
delay evaluation of most types (all but func) from parse time to type check time. R=ken OCL=31585 CL=31585

R=ken OCL=31582 CL=31582
2009-07-10cleanup in preparation for new scoping.Russ Cox1-10/+17
walkstate -> walkstmt walktype -> walkexpr; stmts moved to walkstmt walktype and friends have a final Node **init argument that can have side effects appended, making it more explicit when they do and do not happen. this replaces the old global addtop and addtotop. delete switch map and interface conversion cases (dropped from the language months ago). R=ken OCL=31465 CL=31468
2009-07-08ANY is already checked separately,Russ Cox1-15/+0
so remove code from go.y. show original types in badtype; don't remove pointers. not sure why this was here but it confuses things if the bad part involves two named pointer types with different names but the same pointed-at type. R=ken OCL=31369 CL=31369

2009-07-076g, 8g: generate data structures for new reflect interface (CL 31107)Russ Cox1-58/+0
R=ken OCL=31122 CL=31278
2009-07-06various 6g cleanup:Russ Cox1-21/+31
* give genwrapper and genembedtramp the same signature. * move duint8, duint16, duint32, duint64, duintptr into gc. * tidy genwrapper. * bug involving struct field symbols in signature list. (hash-order dependent so hard to trigger) * new Type print format %#-T like %#T but omits names on function arguments. R=ken OCL=31237 CL=31237
2009-07-06allow conversion to interface typeRuss Cox1-2/+2
when implicit assignment would have been okay. R=ken OCL=31225 CL=31227
2009-07-03maps have == so maps are okay as map keys.Russ Cox1-1/+1
alignment issue is fixed. R=ken OCL=31124 CL=31144

package main type t interface type t interface{ m(map[t]bool) } type m map[t] int making it work without the forward declaration will require a second pass. R=ken OCL=30773 CL=30773
2009-06-25better error; clean up lineno in a few placesRuss Cox1-1/+8

2009-06-23fix a 6g crash after type errors.Russ Cox1-1/+4
do not bother warning about marks left on stack after syntax errors. leave OCONV nodes in tree to avoid type errors arising from multiple walks. R=ken OCL=30639 CL=30662
2009-06-19implement new spec language regarding conversionsRuss Cox1-2/+21
R=ken OCL=30519 CL=30534
2009-06-06gc: grammar cleanup:Russ Cox1-24/+23
* no longer distinguishes const, var, type, package names. * all the predefined names are not tokens anymore. R=ken OCL=29326 CL=29985

R=ken OCL=29907 CL=29907
2009-06-04more 8g progress.Russ Cox1-2/+5
likely to go back to registers for most temporaries. most tests in lib pass. these fail: datafmt fmt go/scanner log reflect strconv template R=ken OCL=29896 CL=29898
2009-06-02minor cleanup, 64-bit /= and %= on 32-bitRuss Cox1-0/+92
R=ken OCL=29806 CL=29808
2009-05-27clean up gmove:Russ Cox1-1/+26
* conversions all in one place. * no separate load, store phases; direct memory addressing when possible (this is the x86 after all!). avoids extra registers, extra MOVQs. * fixes int32 -> uint64 bug (was zero-extending) R=ken OCL=29482 CL=29484
2009-05-268g: 64-bit arithmetic and assorted bug fixes;Russ Cox1-30/+34
can run 64-bit sieve and powser. interfaces are limping along. next hurdle is floating point. R=ken OCL=29418 CL=29423
2009-05-25static init reenabledKen Thompson1-0/+1
R=r OCL=29358 CL=29358
2009-05-231. check for dups in complex literalsKen Thompson1-1/+4
structtype{a:1, a:2} maptypetype{"xx":1, "xx":2} arraytypetype{5:1, 5:2} 2. bug in registerization concerning alias of a struct and one of its elements 3. code optimization of struct.field (which exposed bug in 2) R=r OCL=29315 CL=29315

R=ken OCL=29209 CL=29216
2009-05-20change representation of interface values.Russ Cox1-4/+4
this is not a user-visible change. before, all interface values were struct Itype { Sigt *type; Sigi *inter; void *method[n]; } struct Iface { void *addr; Itype *itype; } the itype is basically a vtable, but it's unnecessary if the static type is interface{ }. for interface values with static type empty, the new representation is struct Eface { void *addr; Sigt *type; } this complicates the code somewhat, but it reduces the number of Itypes that have to be computed and cached, it opens up opportunities to avoid function calls in a few common cases, and it will make it possible to lay out interface{} values at compile time, which i think i'll need for the new reflection. R=ken OCL=28701 CL=29121

2009-05-07if a struct s contains an anonymous interface valueRuss Cox1-1/+17
with method m, s.m() is ok and m now shows up in s's method set for interface runtime. see http://cl/28419-p2 for new test interface10.go. R=ken OCL=28420 CL=28423
2009-05-066g: new interface rules (code got simpler!)Russ Cox1-119/+73
R=ken OCL=28374 CL=28378
2009-04-14tweak interface warning heuristic.Russ Cox1-1/+2
some day i will fix this for real. R=ken OCL=27468 CL=27468
2009-04-09change representation of stringsKen Thompson1-2/+2
R=r OCL=27293 CL=27293
2009-04-08yet another attempt at auto-linkingRuss Cox1-2/+2
store only the original import path string (+ .a) if 6g resolves it to an archive file. let 6l re-resolve the .a at link time. this lets libraries build against an archive in the current directory but get used against an installed archive. R=r OCL=27244 CL=27244
2009-04-02type n t;Russ Cox1-1/+1
was copying a bit too much about t into n, like whether the signature was queued to be printed. (bug reported by anton) was also editing t, meaning you could do type T int; func (p int) Meth() { } both fixed. R=ken OCL=27052 CL=27052
2009-04-02use separate lex buf for better errors:Russ Cox1-1/+1
package main func main() { func(){}() + + } x.go:2: syntax error near _f001 becomes x.go:2: syntax error near func R=ken OCL=27047 CL=27047

signature generation) into gc. R=ken OCL=26933 CL=26933
2009-03-30move some portable pieces of 6g/gsubr.c into gc/subr.cRuss Cox1-0/+240
int brcom(int); int brrev(int); void setmaxarg(Type*); Sig* lsort(Sig*, int(*)(Sig*, Sig*)); int dotoffset(Node*, int*, Node**); void stringpool(Node*); void tempname(Node*, Type*); R=ken OCL=26922 CL=26922
2009-03-24throw away most of the compat.h compatibility layerRuss Cox1-2/+2
in favor of the lib9 compatibility layer. no need for two. now that mycreate is gone, .6 files are 0644 not 0755. TBR=r OCL=26679 CL=26679
2009-03-17binary search on type switches.Ken Thompson1-8/+11
new feature 'case nil:' in type switch will match iff the interface is nil. R=r OCL=26404 CL=26404
2009-03-16change format of Sigt and SigiKen Thompson1-5/+0
to allow room for type hash needed for log-time type switch. R=r OCL=26354 CL=26354
2009-03-12make 6g constants behave as ken proposes. (i hope.)Russ Cox1-117/+40
various bug fixes and tests involving constants. test/const1.go is the major new test case. R=ken OCL=26216 CL=26224

2009-03-11complain when trying to put T into an interfaceRuss Cox1-3/+14
if T has pointer methods. this is just a heuristic but it catches the problem robert ran into and lets me put the larger interface issues aside for now. found one bug in pretty. R=ken OCL=26141 CL=26141
2009-03-061. type switchesKen Thompson1-0/+1
2. fixed fault on bug128 3. got rid of typeof 4. fixed bug in t,ok = I2T R=r OCL=25873 CL=25873
