before fs check - it can ruin the filesysem.

Smaller C: Improve initialization of variables
 2015-05-23 01:50:17 -07:00

3afa8e5979 Smaller C: Improve initialization of variables 
- throw away data of string literals inside sizeof, e.g.
    sizeof "a"
    sizeof("a"+1)
- support minimally and inconsistently bracketed (sic)
  initialization, e.g.:
    int y[4][3] = { 1, 3, 5, 2, 4, 6, 3, 5, 7 };
    struct { int a[3], b; } w[] = { { 1 }, 2 };
- scalar initializers can be optionally enclosed in
  braces, e.g.:
    int i1 = { 1 };

6144631bc5 Smaller C: Support structure passing/returning by value on MIPS 2015-05-17 15:28:37 -07:00
Alexey Frunze
4ea521eabf Smaller C improvements 
- type specifiers may occur in any order
  (e.g. "unsigned short int" and "int short unsigned")

- use .rodata/.rdata section for string literals
- arbitrary length string literals (hooray!)
- better concatenation of adjacent string literals
  (now works even across preprocessor directives)

Support .bss section
- -nobss option in smlrc: use .data instead of .bss as before
- take advantage of .bss in smlrc (put a large array into it)

Remove dead/useless code

Remove useless/rarely used features/options:
-use-gp (MIPS)
-flat16/-flat32 (x86)
-seg16t (x86), -seg16 is now the default
-ctor-fxn

Add/change:
- use EXIT_FAILURE=1 instead of -1 in smlrc when aborting
  due to an error

a4bdbd4662 Bugfixes 
- properly sign-/zero-extend returned values, e.g. the following
function must return 255 and not -1:

unsigned char f(void) { return -1; }

- properly decay arrays on the left side of ->, e.g. the following must
compile:

{
  struct {char c;} s[1];
  s[0].c = 'a'; putchar(s[0].c);
  (s+0)->c = 'b'; putchar(s[0].c);
  (*s).c = 'c'; putchar(s[0].c);
  s->c = 'd'; putchar(s[0].c);
  putchar('\n');
}

Also:
- support structure passing/returning by value (x86 only)

1916f8c9da New kernel configuration: chipKIT WF32 board with microSD card on 2.4" LCD TFT display shield. 
WF32 board by itself already has a microSD socket.
It's useless for RetroBSD though, as it is not connected to any
of available SPI ports (must use GPIO instead).

Fortunately, a cheap shield is widely available, which adds a microSD slot
connected to SPI2 pins.
