6
 
7
src/alloc.c:
8
Fixed subtle alignment bug on p. 28.
9
 
10
src/dag.c:
11
Renamed kill to killnodes to avoid possible clash with kill in .
12
 
13
Made address interface function optional.
14
 
15
Ensured that generated locals, even if not temps, are
16
added to the code list.
17
 
18
Avoided calls to undag when errcnt>0.
19
 
20
Changed listnodes so that array types decay to pointers; bug
21
tickled by -n option.
22
 
23
src/decl.c:
24
Moved call to retcode that injects a return at the end of a function
25
into compound so that temps created by retcode will be
26
scoped properly.
27
 
28
Fixed bug in which functions that return const struct S {...} issued
29
an incorrect diagnostic.
30
 
31
Ensure addressed is set for local arrays.
32
 
33
src/enode.c:
34
Corrected type conversions in addtree for ADD+P nodes;
35
stripped qualifiers from pointer types in eqtree and cmptree.
36
 
37
src/event.c:
38
Revise functions called at events so all have the same signature,
39
modulo pointer types.
40
 
41
src/expr.c:
42
With -b, avoid instrumenting  constant ?: expressions.
43
 
44
Fixed bug in wide-character literals.
45
 
46
Fix allocation error for identifiers injected to quell
47
undeclared identifier errors;
48
Correct int type added to addresses in field offsets.
49
 
50
src/gen.c:
51
Made emitasm extern.
52
 
53
src/input.c:
54
Fixed bug in resynch that caused infinite loop.
55
 
56
Added #ident recognition, which simply ignores it.
57
 
58
src/symbolic.c:
59
Revised symbolic back end to emit -0.0 correctly.
60
 
61
Emit flags in symbolic output.
62
 
63
src/bytecode.c:
64
Fixed double output botch in defconst in bytecode backend.
65
 
66
src/dagcheck.c:
67
Added mssing cases in dagcheck's reduce for types signedptr
68
and unsignedptr. Without these, reduce can fail.
69
 
70
src/lex.c:
71
Permit \ to escape newline in string literals.
72
 
73
Fixed scon() so that it accepts and concatenates adjacent wide-character literals.
74
 
75
src/main.c:
76
Fixed long-standing bug in which -n, -b, -C, and -a options caused
77
interface functions to be called before progbeg.
78
 
79
src/mips.md:
80
Fixed FP comparisons to handle NaNs correctly.
81
 
82
Round up framesize to a multiple of 16 for Irix 6.x;

87
modulo pointer types.
88
 
89
Change ftype to build arbitrary prototypes.
90
 
91
Fixed long-standing bug in which -n, -b, -C, and -a options caused
92
interface functions to be called before progbeg.
93
Also, added missing call to space.
94
 
95
Relaxed assertion in loop that searches for
96
embedded CALL nodes.
97
 
98
Emit correct padding in generated -b strutures.
99
 
100
Revised call hook to find CALL nodes embedded
101
at any depth.
102

src/profio.c:
106
Change compare's prototype to conform to ANSI standard;
107
change calls to qsort accordingly.
108
 
109
Fixed implicit assumption that execution point i in file f always

refers to the same x,y. This isn't true for noweb files.
111
 
112
src/simp.c:
113
Made address interface function optional.
114
 
115
Tighten test that avoids folding addressing expressions
116
for switch tables when the offset exceeds 16 bits. Without
117
this addition, lcc can emit erroneous "initializer must be
118
constant" diagnostics.
119
 
120
Revised simplify() so that if doesn't call address to
121
fold (ADDGRP a n) when n exceeds 16 bits.
122
 
123
Reordered tests in MOD+I case so expressions like 6%1 fold correctly.
124
 
125
src/sparc.md:
126
Fixed FP comparisons to handle NaNs correctly.
127
 
128
Added casts in defconst() to emit constants with proper sizes.
129
 
130
Replaced pseudo-instructions st2/ld2 with pairs of st/ld instructions.
131
 
132
src/stmt.c:
133
Fixed botch in 2.16 revision.
134
 
135
Fixed return statement so that "return;" in a function that returns
136
a value returns 0. Similar code is already in decl.nw.
137
 
138
Resynch to distributable version.
139
 
140
Used dynamic variables for loop and switch handles.
141
 
142
Fixed bug in which functions that return const struct S {...} issued
143
an incorrect diagnostic.
144
 
145
Appended a missing \n to a warning.
146
 
147
src/sym.c:
148
Revised 2.19's code for comparing -0.0 and 0.0 so that it works
149
correctly when long double's occupy more bytes than the actual
150
values, as on the x86 under gcc.
151
Fix constant() so that it treats -0.0 and +0.0 as different constants.
152
 
153
Added newtable() to allocate empty symbol tables.
154
 
155
src/trace.c:
156
Revise functions called at events so all have the same signature,
157
modulo pointer types.
158
 
159
Change ftype to build arbitrary prototypes.
160
 
161
Fixed long-standing bug in which -n, -b, -C, and -a options caused
162
interface functions to be called before progbeg.
163
 
164
src/tree.c:
165
Correct revision 2.9's implementation of check to avoid
166
superfluous diagnostics on widening conversions.
167
 
168
Avoid diagnostics for superfluous widening conversions.
169
 
170

173
 
174
Change ftype to build arbitrary prototypes.
175
 
176
src/x86.md:
177
Fixed FP comparisons to handle NaNs correctly.
178
 
179
Changed ARGB instruction sequence to decrement
180
esp by the size of the structure rounded up to 4.
181
Changed struct allignment to 1; this required changing local to
182
insure that on-stack structs are aligned to at least 4 bytes.
183
 
184
Added cast in defconst to eliminate extraneous bits.
185
 
186
Fixed float-to-int conversions so they truncate properly;
187

273
-D__CHAR_IUNSIGNED__ and -U_CHAR_IS_SIGNED to the cpp
274
command line. These options interact with changes to the
275
standard header limits.h to set CHAR_MIN and CHAR_MAX correctly.
276

Insured _VA_LIST is defined.
308
 
309
Revised __va_arg macro to handle va_arg(float) correctly;

313
include/*/*/stddef.h:
314
