Fixes/workarounds:
- octal escape sequence is to be terminated no later than after three
octal digits:
"\1011" is now parsed equivalently to "A1"
- workaround truncation of immediate operands to 16 bits in MIPS
instructions addi[u], subi[u], slti[u], andi, ori, xori in RetroBSD's as
(disabled since as is being fixed).
Improvements:
- warn on string literal truncation when initializing array of char
- generate trap/break-less form of MIPS div[u]
New:
- experimental support for __interrupt functions (x86/huge only)
of 3-reg instructions (add, addu, and, or, slt, sltu, sub, subu, xor).
When mode ".set at" enabled, an additional LI instruction is inserted
sing $1 as a scratch register.
Fixed bug in C preprocessor: buffer size reduced to avoid allocation failure.
Added option -v for smlrc.
New example stdarg.c: a demo of function with variable arguments.
For LCC, please use /bin/lcc instead.
I believe SmallerC is mature enough to try to use it as a primary compiler.
System include files might need some changes (ifdefs) to adapt.
The following global/static pointer initialization should now work:
static char* p1 = "abc" + 1;
static char* p2 = "abc" - 1;
static char* p3 = 1 + "abc";
static int a333[3][3][3];
static int* pa333_111 = &a333[1][1][1];
Other seemingly (and in fact actually) functionality preserving changes
are only to reduce code size when self compiling for DOS using -seg16.
Improvements and fixes require space, sigh.
In the following
typedef struct S0 { char ac[4]; } T1;
int v26 = (int)&((T1*)0)->ac[3];
int v27 = &((T1*)0)->ac[3];
v27 should be initialized to 3 just as v26.
Improvements:
- support initialization of multidimensional arrays
- support initialization of structures
- support initialization of structures and arrays inside functions
- support static inside functions
Notes:
- Only fully-bracketed (sic) initialization of arrays is supported.
- && and || have been partially replaced with & and | to slightly reduce
code size when self compiling for DOS using -seg16.
