#1277 Don't generate ASM code

I don't know if it's really a bug:

The code for lines (59/60)
PORTB = g_vcval[0]; // output DEBUG
CCPR1L = g_vcval[0]; // output PWM
is not generated; the output isn't run.
When change lines 59/60 to:
PORTB = g_vcval[0]; // output DEBUG
CCPR1L = PORTB; // output PWM
the code is generated and runs fine.

version:
SDCC : mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08 2.6.0 #4309 (Jul 28 2006) (MINGW32)

    Well, 2.6.0, r4309 is ancient history... The attached code compiles fine (though freq.c and wave.c are missing...) with SDCC 2.6.4, r4570.
    Please update your installation and try again.

    Thanks for your follow up.
    The latest version in Source Forge is 2.6.0, how I can obtain the 2.6.4.?
    Thanks in advance

    Either use one of the snapshots from http://sdcc.sourceforge.net/snap.php#Windows (most recent one is 2.6.3, r4543 from 31-12-2006, though), or grab the sources from the subversion repository and compile them yourself. As you seem to use SDCC in Windows/MinGW, the snapshot approach is probably preferrable. That revision should be fine for the moment, as I did not change the PIC14/PIC16 ports much this year so far.

    Wrong diagnosis: The bug lies in the (known) faulty pcode optimization still enabled by default...
    Until this is fixed, use `sdcc -mpic14 -p[whatever] --no-pcode-opt [...]' to prevent this overly aggressive optimization from breaking your code.
