Fix static and shared library usage for acc and accRuntimeTest
2009-11-12 16:06:28 +08:00
b5d2ad66df
Build accRuntimeTest with static library rather than shared library.

Skip OTCCANSI test on OS X
...
OS X can't load stderr/stdin/stdout through the DLL symbol lookup
interface, so it can't compile the otcc-ansi.c test.

464407588f
Build acc tool with static rather than shared library.
...
OS X does not allow relative shared library path names in compiled apps,
so we have to create and link with a static library version of libacc.

am 556c60f4: am 51da51a2: am 02effee6: Correctly compute the type of an assignment expression.
...
Merge commit '556c60f4f27e2a3bfde6a47acf876716ea8d5795'
* commit '556c60f4f27e2a3bfde6a47acf876716ea8d5795':
Correctly compute the type of an assignment expression.
2009-11-09 16:28:51 -08:00
02effee6a9
Correctly compute the type of an assignment expression.
...
This change enables following types of statements to work correctly:
a = b = 3;
if ((a = getchar()) < 0) { ... }
This fixes 2232082 acc: assignment in comparison segfaults

Add support for the continue statement
...
Add error check for a break statement that's not inside a loop. (We just
generated bad code before. Oops!)
2009-10-29 15:04:27 -07:00
ee1f829dd4
Implement typedef.
2009-10-28 16:10:17 -07:00
188a5a7a3a
Support nested macros. (Still don't support macro arguments.)
...
Now you can say:
#define A B
#define B C
#define C 4
int x = A;
And it will work as expected.
Print an error message rather than assert when we're expecting a
function value, but don't find one.

66d487487f
Print out error message when symbol lookup fails.

Add back missing libdl in linker command. The executables here contain call
...
to function defined in libdl.so but the library is missing the linker commands.
Currently, the library is linked via dependency of another library. While this
works, it is not the right thing to do.
2009-10-02 12:02:02 -07:00
1c60e46e0e
Produce error rather than assert when encountering a nested function.
...
Remove extra '\n' characters from error messages.
Dynamically allocate error message buffer.

Add a script "accarm" for ad-hoc testing of the ARM acc compiler.
...
This script copies the test file over to the ARM, runs the acc compiler
on ARM, and then prints out the results.
It also syncs the acc compiler binary over to the ARM.
2009-09-10 12:45:31 -07:00
d5315573d7
Move ARM disassembler out of libacc and into the acc command-line tool.

Improve address operator (unary &).
...
Until now the address operator only worked with simple variables.
Now it works with arbitrary expressions (that are lvalues or function
names). So for example this now works:
struct S { int a[10]};
int f(struct S* p) {
return &p->a[3];
}

Preliminary struct and union support.
...
Working features:
- struct
- union
- nested structs
- anonymous structs
- forward declarations
- '.' and '->'
- copying structs using '='
Missing features:
- passing structs by value
- returning structs by value
- typedef
- sizeof
Example:
struct v {float x, y, z, w; };
void add(struct v* result, struct v* a, struct v* b) {
result->x = a->x + b->x;
result->y = a->y + b->y;
result->z = a->z + b->z;
result->w = a->w + b->w;
}
Reworked size-of and alignment logic to support structs.
Improved encoding of ARM immediate constants.

Make pointer casting work.
2009-08-25 12:23:43 -07:00
0f400c59b8
Add runtime check for whether or not the OTCC-output tests can be run.
...
This means we don't have to manually specify the --norunotcc flag.
2009-08-25 11:57:13 -07:00

Add a --nox86 flag to allow disabling x86 tests
...
The x86 tests don't work on non-Linux systems.
2009-08-19 11:12:56 -07:00
0a01a5db56
Handle functions with anonymous arguments
...
Example:
int f(int a, int, int c) {
return a + c;
}
2009-08-19 10:53:43 -07:00
815d8b8fdb
Allow redefinition of macros.
...
Example:
#define A 3
#define A 4
This used to do strange things, but now works as it should.
2009-08-18 18:25:56 -07:00
0b1827a5b2
Allow '//'-style comments in #defines.
2009-08-18 17:44:12 -07:00
0b2de0de64
Allow parenthesized expressions as the value of defines
...
For example, this now works:
#define A (1 + 2)
Note that we still don't support defines with argument lists, so this is
still illegal:
#define A(X) (X + 2)
Also in this change: The compiler test script allows command-line
arguments to disable testing on ARM and to disable testing the output
of the old OTCC compiler.
Disabling testing on ARM is handy for developing front-end code when no
device or emulator is available.
Disabling testing OTCC output is handy for some 64-bit Linux environments,
because the original OTCC needs some tweaking to be fully compatible, and
I don't have time to investigate this problem right now.

used.
