Use fwrite to write $display output, instead of fprintf
...
This change makes it safe to write non-ascii characters, which
is an issue when the %u format is used.

Add -i (interactive) option to vvp.
...
This forces <stdout> to be unbuffered. This is useful when using the
mintty terminal emulator in Windows (as used by MSYS2 and CygWin),
which identifies as a pipe, not a tty.

Fix for GutHub issue #64 - vvp interrupt/continue in Windows.
...
Windows implements the original UNIX semantics for signal(), which
means you have to re-establish the signal handler each time a signal
is caught.

Update man pages.
...
Removed obsolete -m32 and -ivl options from iverilog-vpi man page
and revised description of -mingw option. Also removed duplicate
descriptions of --cflags, --ldflags, and --ldlibs options. Updated
link to main iverilog web page in all man pages.

Enable use of MinGW ANSI stdio routines.
...
Defining __USE_MINGW_ANSI_STDIO=1 provides C99 compatible printf
and scanf routines, which avoids the need for workarounds for the
various failings of the Microsoft C runtime library.

6a3edc63d5
Fix printf format for size_t values when using 64-bit MinGW.
...
The Microsoft C runtime does not support the %zu and %zd formats.
Previously these were replaced with %u and %d, but for 64-bit we
need to use %llu and %lld.

45dc13e496
Use uintptr_t/intptr_t when casting between pointer and integer.
...
The code was using (unsigned) long, but a long is 32-bits in the
Windows 64-bit ABI.

Fix vvp crash when a part select of a wire is passed to $monitor.
...
When the PV expression is compiled, the parent net may not yet be
resolved, so we may not be able to get its VPI handle straight away.

Fix for br968.
...
__vpiVThrVec4Stack::vpi_get_value_int_ was always treating the thread variable
as unsigned, rather than observing the value of __vpiVThrVec4Stack::signed_flag_.
Not sure why this was done - none of the regression tests broke when I changed
this.

0282b8450c
Fix potential memory leak when a thread is disabled.
...
A disable statement can terminate a thread whilst it still has
local variables on the stack (e.g. the loop counter for a repeat
statement). We need to clear the thread stacks when this happens.

Use uint64_t casting of constants since UL does not work on 32-bit machines
...
Using a UL constant in a unit64_t context does not work on a 32-bit
machine since UL is 32-bits. Instead create uint64_t constants using
static casts and the appropriate bit operators.

better add performance.

Optimize the vec4-stack %cmp/s and %cmpi/s instructions.
...
Magnitude compare is called a LOT, so it is worth putting some
special effort into it.

Reduce some vector copies in %load/vec4 and %concat/vec4 instructions.
...
By clever stack manipulations, we can eliminate some vector copies,
which can improve performance.
2014-12-03 13:12:06 -08:00
85c7b07a9b
Implement %cmp/ne and %cmpi/ne
...
These pull in the inversion of the output flags so that they more
efficiently implement != and !==, without %flag_inv instructions.
2014-12-03 11:06:11 -08:00

vvp implementation of copy from vec4 to vec2 can use subarray method.

b83144c552
The __vpiArray::set_word method should take a reference.
...
Seem to have missed a case where a vvp_vector4_t can be passed by
const reference instead of by value.
2014-12-02 13:02:46 -08:00
