Full checking -appears impractical, but there's still more than than there was -before. - -On the SPARC, lcc now emits .type and .size directives -unconditionally. - -On the x86, constants are now emitted into the text segment. - -If the environment variable "LCCDIR" is defined, it gives the directory -that contains the preprocessor, the compiler proper, and the -lcc-specific libraries. - -Under Windows, lcc searches the directories named in the environment -variable "include" for header files. - -Errors fixed: - -Erroneously complained about unknown sizes for some const fields, eg, -typedef struct foo ref; struct foo { const ref *q; int a; }; -f(ref *p, int i) { return p->q[i].a; } - --A -A erroneously complained about static main's that didn't conform -to the ANSI-mandated "int main(void)" or "int main(int, char **)". - -Silently generated incorrect code for a structure copy with a -post-incremented target, eg, -struct { int x; } data = {1}, copy[2], *q = copy; -main() { *q++ = data; } - -Generated incorrect values in some expressions with constant pointers. - -Silently truncated string literals longer than 4095 characters. - -Failed to emit debugging information for uninitialized globals. - -Failed to diagnose missing sizes in some multi-dimensioned array -declarators, eg, extern int x[][10]; int x[5][]; - -Silently emitted incorrect sizes and initalizations for some -incomplete multi-dimensioned arrays involving pointers and whose size -is determined by the number of initializers. - -Set only the x.name field for some back-end symbols (eg, wildcards), -and the uninitialized name field crashed some debugging output. - -uses() failed to check the register *set* as well as the register -mask. There's no known bug demo, but a wildcard set might be -contrived that would need the test. - -Crashed with -b on some conditional expressions involving calls, eg, -int p; void g(void) { p ? f() : 1; } - -On the MIPS, sometimes generated an incorrect frame size and thus a -crash when floating-point registers were saved. - -On the SPARC, erroneously reused a register variable as a temporary -when the variable is compiler-generated. - -On the SPARC with -b, emitted incorrect code for returning structs. - -On the x86, conversion from float to int rounded instead of truncated -with the default floating-point mode. - -On the x86, eliminate rtargets for kids after the first (see p. 419). - -On the x86, substitute reg for freg, in order to use the common reg -rules. Needed only for debugging output, since we're not using any -float regs as regs at this time. - -On the x86, "double f(); main(){f();}" wasn't popping the FP register stack. - -On the x86, ECX was saved by the callee, when it should have been -saved by the caller. - -$Id: LOG 145 2001-10-17 21:53:10Z timo $ -- cgit v1.2.3
